Are you married? How are you filing? Aren't you filing a Married filing Joint return? Her return might be rejecting if you already included her ssn on your return. Or is she your dependent? I think we need more details. Whose returns are rejecting and what exactly is the reject message or code? A duplicate return usually means a ssn number has already been filed on someone else's return. If she is your dependent then she has to check the box that says she can be claimed on someone else's return. Go back though My Info or Personal Info and look for that question.
