Last year I was able to efile one or two amended returns, but the 2020 return that I am trying to transmit today shuts down when I am trying to convert it after saying it is ready to efile and saving. I did the original return, used the original file, etc. The message says "transfer was unsuccessful, internal error". I have updated the program, do I need to close and reopen? The only thing I am changing is asking for the second EIP, which the taxpayers thought they were going to receive but did not.
