Updating an array in SharePoint spfx using React & PnPJS

I'm creating a web app that allows the user to update their status and location.

I have a data list table on SharePoint with the user's name, email address, status (for example: online, offline, or busy), location (which is a select field), along with other fields.

The web app is just 2 different select fields. Which allows the user to update his status and location.

When the user accesses the page on componentDidMount() I'm getting the user's email addresses (since he's logged into SharePoint) and then filtering the data list array to view the element for his information (so looking for his email address in the MyList. The part I'm stuck at now is updating the MyList list with the selected response that the user selected.

Using PnP-JS i found this should be possible here are two links showing the update() function. https://github.com/SharePoint/PnP-JS-Core/wiki/Basic--Operations

My code found here:

export default class SigninLocationWebpart extends React.Component<ISigninLocationWebpartProps, {Status: string, Location: string, userName: string, getEmail: string, selectedUser: any}> {

    constructor(props) {
        super(props);
        this.state = {
            Status: 'Online',
            Location: 'New York',
            userName: '',
            getEmail: '',
            selectedUser: {},

        };

        this.handleChangeStatus = this.handleChangeStatus.bind(this); 
        this.handleChangeLocation = this.handleChangeLocation.bind(this);   

    }

    handleChangeStatus(event) {
        const { value } = event.target;
        this.setState({ Status: value });
    }

    handleChangeLocation(event) {
        const { value } = event.target;
        this.setState({ Location: value });
    }


    private _onUpdate(event) { 
        event.preventDefault();

        //This is where I need help on updating list
        let list = pnp.sp.web.lists.getByTitle("MyList")

        //Instead of getting by ID i need to get by that selectUser array I believe
        list.items.getById(1).update({
            Status: this.state.Status, //User changing from Online to Offline
            Location: this.state.Location //User changing from New York to Los Angeles
        }).then(i => {
            console.log(i);
        });

    }       

    public componentDidMount() { 
        if (Environment.type === EnvironmentType.Local) {
        }
        else if (Environment.type === EnvironmentType.SharePoint || Environment.type === EnvironmentType.ClassicSharePoint) {

            //This gets the current users info and sets it to username and email
            sp.web.currentUser.get().then((response : CurrentUser) => {
                //console.log(response);
                this.setState({
                    userName: response["Title"],
                    getEmail: response["Email"],
                })
            })          


            //This gets the list of all all items in the list
            pnp.sp.web.lists.getByTitle("MyList").items.get().then((items: any[]) => {
                console.log(items);

                //Comparing email from sign in user and filtering items array to get that element
                var compareEmail = this.state.getEmail;
                console.log(compareEmail);

                let selectedUser =  _.filter(items, function(item) {
                    return item.Email_x0020_Address.toLowerCase() === compareEmail.toLowerCase();
                });
                console.log(selectedUser);


            });


        }
    }



    public render(): React.ReactElement<ISigninLocationWebpartProps> {
        return (

            <div className={ styles.signinLocationWebpart }>
