Thank you, Lisa. 

I read your response. I too followed the PS instructions and saved a copy. I only saw this thread after I started seeing things that don't look correct after I amended returns following the PS instructions. I made the amended changes per the PS instructions and, as you suggested, in the original file for both the federal and Colorado returns.

The amended return displays as Federal amended and CO amended in the Pending EF Center Return Type. However, the EF Center shows the eSignature Status as completed and the Amended Return column shows "Marked for EF".

However, the original saved copy also appears in the Pending tab of the EF Center and the eSignature Status says "Not Started"  and allows me to request eSignature. This seems backwards since the request eSignature option isn't allowed for the amended returns. The eSignature status for the saved copy says "Not Started". The Return column also says "Marked for EF". 

Are we not allowed to send amended returns for eSignature? If we are able to then how do we do that since the "Request" option isn't available?

Also, the EF Status for the copy file and the amended returns shows "Duplicate SSN/EIN". I remember that I wasn't able to e-file returns in the past when duplicate SSNs were shown.

Will I have a problem e-filing the amended returns with the duplicate SSN?

Thank you for your help.
