Wordpress advice - quick problem to solve

I am having an issue with a website page. I have a web page where there are web forms at the bottom of a page that appear on the page but that don't show in the editor. I am struggling to find where they are in the system to delete them. I just need someone to walk me through how to do this. I anticipate it being something super easy to fix so it's a 15 minute job either phone or screen share.
