In the search box on the left use "amend" to find 1120F Amended Electronic Filing. 

I hope that helped

Hello George:

Thanks very much for your suggested remedy.

One of the things that I forgot to mention was that the 1120-F we are attempting to amend was a paper-filed return. If the return was electronically filed, your advice would have been spot-on.

Thanks again for your help!!!

Prepare the return to match exactly the way it was originally filed, then follow the instructions to Amend
