You may only e-file once. So, only your first submission counts. If you need to change anything officially, you would have to file an Amendment Form 1040X by mail.
You will need to wait
to see if your original return is accepted or rejected. If rejected, you may correct
and resubmit. If it is accepted, you will
need to file
an amendment. Please reference this
TurboTax FAQ for how to amend.
