Plasma 5.20 was pushed to testing today for F33: https://bodhi.fedoraproject.org/updates/FEDORA-2020-d700fa11cf
I would recommend you avoid it for the time being. It causes a black screen when starting Plasma Wayland. I’ve opened a bug report here and gave negative karma: https://bugzilla.redhat.com/show_bug.cgi?id=1897717
Update 11/16/2020: The black screen issue seems to be limited to using Radeon Graphics in conjunction with the SDDM display manager with Wayland. One quick workaround if you have a Radeon card would be to use the GDM display manager instead of SDDM. If you keep that in mind, you should be good to go with testing. Please report any issues to bugzilla - this will help the effort to identify and correct issues so Wayland can become the default in KDE Fedora.
If you are just wanting to use X11, it seems to work fine regardless of displaymanager or graphics card.
