How to make Jellyfin and tinyMediaManager work together?

I must be doing something wrong, then.

I figured out what I needed to do!  Posting it here in case someone else finds it, even though it's probably in the documentation somewhere.

1. Create the Jellyfin library.  Select whatever metadata options you want but ***don't*** check Metadata savers > NFO.
   
2. Identify the problematic show in tinyMediaManager by doing Search & scrap selected TV show(s) on its folder.
   
3. Plug in the show's TMDB number, found in the URL.  For Azumanga Daioh, it's (currently) 12143, so plug in TMDB:12143.
   
4. There should still be no NFO files in your media folder.  You can check with find "/path/to/folder" -type f -iname "*.nfo".
   
5. Write the information you had tinyMediaManager to NFO files with (right click) Enhanced editing > Rewrite NFO for selected TV shows(s).
   
6. Rescan the library in Jellyfin, which I did just using Scan All Libraries.
