"Do not file form not final" is on my Downloaded copy of Fed 1040. Missing the normal cover sheet shows balance due/ when refund/ what keep/ 2020 tax summary. Problem?

Yes, the normal cover sheet and 2020 tax summary pages are all there once you complete the return.

I show that the print copy of the 1040 is available now.  You need to update your software and then your return and -filed and review your copies again to see if you are still getting the message on your Form 1040.

If the e-file was accepted, then you don't have to wait for the print approval to file your return!  A great advantage since it was already filed!

Your paper copy of the 1040 for your return since it was e-filed and accepted should have a different message on it now.  It should say do not file since it was already e-filed.
