My only problem is that if we have already e-filed the 940s and they eventually go through (no confirmations yet on any) and then we mail them, will it create a duplicate filing? The 940 is the only form I have an issue with. 941s go through, and we file all other reports directly with the state agencies. 

I agree on use of EASY. I am already searching for another software provider with write-up simplicity. Very disappointing all around, especially communication.
