I am faced with the same dilemma.
After amending my return, I went into the e-File tab as the program suggested and was able to complete the verification. But when I got ready to file, it asked me to input the current date (02/23/2021). When I did that, I received an error saying that the date entered had to be between 01/01/20 and 12/31/20. It would allow me to change the current date, but I hesitate to do that as I am concerned that backdating might invalidate the return.
Has anyone else experienced this situation?
