I am getting 4 error messages on my 2021 amended return, and they are all the same except for a # variation.   The error doesn't go to a particular box on the 1040X, so I can't find the source of the error.

"1040X: Ofrl2 is marked as estimated, please fill in correct # and select unmark estimated from the edit menu."

I keep going to line 2, 4b, 6 and 9 (which is not a line) deleting and unmarking as per the instructions.  Error does not go away.  

I want to e-file this amended return, not a paper copy that will never be processed.
