Anyone have any experience E-filing an amended state return only?  In NC we have to amend a ton of 2020 state returns for the PPP loan forgiveness.  Note - the federal return does not need to be amended.  I cannot figure out how to populate a new NC e-file return for the amended.  I've marked the "file state amended return" box on Federal return.  A drop down window opens and North Carolina is a choice, so obviously I choose it.  Enter the changes on the amended NC return.  But how do I convert and create the new file to be amended?  When I currently choose "covert/transit"....the message is that the file has already been transmitted.  ANYONE else have any ideas?
