I have my 1040-X ready to e-file but Lacerte is coming back with:

"Client Selection - Unable to e-file Amended Return(s).

The following clients will not be included in the e-file return processing.  Refer to the client note for explanation on why the client is being excluded.  Would you like to continue without these clients?"

the Note says:  "Client is not setup for any amended returns that can be e-filed."

This client's 2019 original 1040 was e-filed by a Senior Center volunteer AARP tax preparer.  I have the original signed form 8879, so I know it was e-filed.  Does it make a difference in Lacerte if I was not the original ERO?
