At this point in time, the best you can do is be patient. You will need to amend your tax return to change the claim of a dependent, but you need to wait until your filed tax return has been accepted by the IRS. When you are ready to file your amended return, TurboTax will guide you through the process. Please follow the instructions below, and remember that amended returns are not accepted for e-filing by the IRS. You will need to print, sign, and mail your Form 1040X, with a copy for all changed forms and schedules to the IRS Service Center serving your region.
