I went back and deleted the entry I had made before (apparently you

careful to place strings within apostrophes. I was then able to boot
that entry. It did a selinux relabel during the boot, but I have now
booted back into Fedora 33.
Thanks for both the clarification of your problem, and for posting the
working solution you found.
