Issue resolved, see below.
I had a backup drive going, TM working on it, then decided to erase it and reformat from APFS to Mac OS Extended. Then I did what I should have done first, and searched for information. But, I found out that TM is supposed to work with either of the above, although APFS is preferred. So I changed it back to APFS, but TM still says the drive is not found, even after a Restart and then Eject and unplug, wait, and plug back in. What should I try next?
Edit: I went into TM Settings and removed all volumes from the target list, then added the volume back, and the backup proceeded.
