Amend
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.
The link below will have the steps to Amend. 2016 Amend forms will not be ready
