I have had the same issue and no idea what I am doing wrong. So you are not alone. NOthing I have tried works. I have a message in to an Admin so will see if that produces any thing.
Here is my post from earlier this month:
Just tried and it did send to the IRS, then came back as rejected. Same message. Says the 1040-x is not in the return.
If I hit "EF Now" from within the client instead of from EF Center, the amended return boxes are blanked out and it is looking for me to check the original return boxes.
I wonder if I need to somehow purge the Efile records for this client. I have now tried to file it 4 times. I did copy the file over to a new name yesterday and rechecked all the boxes. I just cannot get this to go. I know for a fact the first one was efiled, as I had the acknowledgement from the irs and "wheres my refund" shows refund on original return was issued.
