So getting Parallels to work with Manjaro v20 (and probably v19 since parallels only says they support v18) was a pain in the butt and it took a lot of resources from a lot of places to figure it all out. I figured I would post some information here on things that I ran into and how to fix each of them.
This is from a completely fresh installation from the v20 isos but steps may be applicable in places for upgrades if you run into similar issues.
I got this all working finally:
Manjaro Version: 20.0 Desktop Environment: KDE
