I am trying to amend a return that I did not originally do. When trying to efile the 1040X the software is telling me that I cannot amend because the return has not been efiled with the IRS. The client did it herself through Turbo Tax and made a mistake. I tried to trick the system and tell it that it was filed in the Client Status form, but that did not work either. Are there any secrets to Efile a 1040X from a Client who efiled her own 1040?
