How do I ignore or get rid of the branch I created?

[Aliah Hutson]

I'm new to SourceTree.  Using Mercurial.  I just want to push the newest local changes and ignore (or delete) the branch completely. I tried closing it, but it's still there and now wants to push the closed branch (I think).  I don't think I want to do that, I didn't push the branch when I created and then undid those changes. This is probably where my issue started, I don't think I handled the reverting correctly.

I am fine if I need to revert to an older version, but I am not sure how.  The options when right-clicking are different than what is online when I search.
