I've always created a copy of the file to amend a return, prior to the e-file option in 2020. I e-filed 3 on Monday using the first procedure but now I can't seem to get it done with the new procedure.

So have you e-filed an amended return since Monday without making a copy or following the current instructions. I have Paper and PDF Copies of the original return so I'll try amending the original file and see if that works. Thanks for your help.
