I have had that problem; I think if you did not efile the original return, you are not able to efile an amended. I have been able to amend returns I efiled, but have never been able to efile an amended return that someone else efiled. which doesn't make sense, only time I amend a return I prepared is if my client forgot something or got a K-1 2-4 months late!
