Board Thread:Support Requests - Getting Technical/@comment-31665266-20200920213439

I am a discussions moderator on a wiki that was recently utilizing forums; however, after forums were retired, a category called General was added to our new Discussions section. Our wiki has no need for such a category because it is a duplicate of another category that shares almost the same name. How would I delete this category? I recall forums had a page for board management, but I cannot find the discussions equivalent.
