A 1040x form is the form you file when you make a change to your original tax return. First you will need
to wait and see if your return is Accepted or
Rejected by the IRS. If the return is Rejected you can go back in and fix the mistake
without amending. If the return is Accepted
you will need to WAIT until you receive
your refund and then Amend your return.
