Custom Tax Archive of Parents Only?

I’ve managed to figure this out myself, so if anyone out there needs some help please try the following…

Using the get_terms rather than trying to query it directly.

<?php 

                    $terms = get_terms('custom-tax-name', array('hierarchical' => false));
                    foreach ($terms as $term) {


                    $term_link = get_term_link( $term );

                     if ( have_posts() ) :

                 ?>


                     <a href="https://wordpress.stackexchange.com/questions/199223/<?php echo $term_link; ?>">
                     <?php echo '<h3>'.$term->name.'</h3>'; ?>


                    </a>

                <?php endif; wp_reset_query(); } ?>
