If you filled out the non-filer form it generated a simple 1040, that's why you can't e-file because of a duplicate SS#. When you look up the return it says accepted, so one has been filed correct? W That is correct that only FILED returns have the 3 year period. I didn't overpay, I paid what was owed. I had this amount way before I filled out the non-filer from turbotax.
