Can't get rid of IPTV channels

[hornakapopolis]

Did you place your M3U tuner file in a library directory?

I don't recall exactly where I had it and that's mainly because it's nowhere I would have put it; nowhere Jellyfin has access; nor is it the other location on my NAS where I might have decided to put it. My memory sucks, so I have to stay as organized as possible. Should it have been deleted when I removed it from Jellyfin? I typically keep everything, too, but am pretty sure I deleted this so that I didn't accidentally install it again in the future thinking I saved it for a purpose.

Did some testing.  I had to remove both the tuner and guide data then "Scan all libraries".

When you say 'Guide Data,' is that what appears in the 'TV Guide Data Providers' dropdown? I deleted that within minutes of installing it once I found out how many channels it had. If it's something else, then I'm not sure how to do that or where to do it.

I deleted my tuner a day or so ago. I ran the 'Scan all libraries' when it was suggested above and just ran it again for good measure. Right now, my 'Live TV' page in the dashboard is blank. It looks like...

   

I really do appreciate this.

Is there a place in the database I can go to get rid of this?
