Do you mean you can’t show a taxonomy archive page.
There are other templates that are related to taxonomies. The first is
archive-somename.php
That will show an archive of all posts in a post type
Then there is
taxonomy-$taxonomy.php
where $taxonomy is the name of your taxonomy. This will show an archive of the taxonomy posts.
I was going to point you to the WP template hierarchy document, but it appears they’re in the middle of some kind of switch, the page should be here https://developer.wordpress.org/themes/basics/template-hierarchy/ but redirects to something new that isn’t their yet, how nice.
On top of that you’re working in the Genesis framwork, and that has it’s own set of rules. Functions like the ACF function the_field() will work anywhere that a standard WP function like the_content(); will work. You need to figure out how to add basic functions and for that you really need the Genesis documentation.
