Stuck With Big Sur

it seems I could be stuck with Big Sur. My attempts with Internet Recovery has failed.

Reformatted the Hard Disk to HFS+ but now I am back to APFS and Big Sur.

I get a error message that the install '(MacOS Catalina) failed.

Never buy version 1.0 of anything.
Don't it always seem to go
That you don't know what you've got
Till it's gone
They paved paradise
And put up a parking lot
