Unable To Update To Catalina Update

I have been unable to update to the latest Big Sur developer beta on the new iMac (2020) I just purchased. I installed the developer profile as usual, and went to software update, and I get the latest Safari developer seed, but nothing else. When I install my developer profile and it auto searches for the Big Sur update I get a message that states 'Update not found: The requested version of macOS is not available.'

I have had no luck getting it to find the update. I've tried re-starting, checking the App Store, trying to unenroll and re-enroll the developer profile, I've tried the public beta profile, but nothing has helped. I was been able to install the beta on my 2019 iMac just fine. Any suggestions?
