How to remove comment form tags?

try either:

add .form-allowed-tags { display: none; } to style.css of the theme, or to whatever way the theme adds edited styles; possibly with a custom css plugin to keep the edits during an update of the theme.

or:

find comment_form() in comments.php (?) of the theme and change that to <?php comment_form(array('comment_notes_after' => '')); ?>

Thanks, but the first suggestion didn’t work and don’t understand the php one. If I do the php suggestion I will need to put it into a child theme and no clue exactly what to put there? Only the code you typed above? Put that in all by itself??? I really don’t want to use a child theme as it’s not really necessary for this theme for what I want to do. Any other CSS suggestions that might work that I can just add to my plugin CSS Manager?

Oh, I am soooo sorry, your first suggestion DID work perfectly! It was just me, I had an extra word in there by mistake.

Thanks!
