Does anyone have insight on how to resolve failed transmission due to Error 703?  After speaking with Lacerte customer support, I don't have a better understanding what the difference is between this error message and the fed reject "R0000-902-01: Taxpayer TIN must not be the same as a previously accepted return" besides that the failed transmission has not been sent to the IRS.  Are these returns stuck in limbo? Is there a way to verify if these taxpayers have been victims of identity fraud?
