You have to use simple wordpress function to check is a user logged in or not. is_user_logged_in()

Checks if the current visitor is a logged in user. it returns (bool) True if user is logged in, false if not logged in.

  <?php
    if ( is_user_logged_in() ) {
        echo 'Welcome, registered user!';
    } else {
        echo 'Welcome, visitor!';
    }
    ?>

First you need to check user in on checkout page or not, if so then do the checking; or if you have your own function then you can simply wordpress is_user_logged_in() function.

add_action('wp', 'xyz_checkLoggedIn');

function xyz_checkLoggedIn() {
    if (is_checkout()) {
        if (is_user_logged_in()) {
            //user is logged in
        } else {
            //user is not logged in
        }
    }
}

Code goes in function.php file of your active child theme (or theme). Or also in any plugin php files.
The code is tested and fully functional.

Hope this helps!

function check_if_user_loggedin() {
if ( is_user_logged_in() ) {
    echo 'Logged user';
} else {
    echo 'Guest user!';
}
}
