I upgraded to Catalina with at least 100GB of free space on my hard drive. Since updating the free space has gone down to 17GB. I tried running Time Machine but it gave an error that "2 drives had the same name, change one." I did that. See attached photo. What happened to my free space?

200 GB is not a huge amount of space these days. The upgrade to Catalina uses at least ~20GB, then you may have had apps auto-upgrade in the background to take advantage of Catalina's new features, using up even more space.
It looks like you have a lot of TV shows on your drive. How about moving a bunch of older ones to an archive disk, thereby freeing up space on your main one?
