comment_form($post_id) not using $post_id, but last created post

Hello,
I’m trying to use comment_form to put comments to specific post (50 for example) but comment form uses last post created and on ridirects to 404 with last post made.

I want to make comments connected to specific post and on same page read them.
I have scroll page website.

Checked DB it makes new posts connected to wrong post (last created)

this part of the code
‘comment_form( 14 );

$replies = get_comments( array(
‘number’ => 30,
‘status’ => ‘approve’,
‘post_id’ => 14

));’
What can I do?
Thanks a lot in advance!
