Welcome to the forum.
So don't include it in the TOC. The TOC only contains what
you choose to put in it. If it is already there, highlight it in
the TOC and hit Delete. It only removes the topic from the TOC, it
doesn't delete the topic from the project or the output.
Don't forget a search could find the topic. If you want to
hide the topic from a search, there are a number of posts on the
forum covering that.
