Thank you for the reply, ljr.  I did everything you mentioned, except select "efile" in the original return.  I guess I have to now go back, delete the amended return, click the efile box in the original, create a new file, and then recreate the amended off of the new file.  There is not that many steps in creating the amended, so that shouldn't take much time.  

I will try to click the efile in the original first, to see if that works.
