We advise people to mail in the return when someone else has claimed a dependent and a efile is rejected. This happens when one parent claims a child and the other person was entitled to claim the dependent that year.
In your case, an amendment will be the correct way to go. No one is going to say that they are entitled to claim her.
Amend will not be available until the IRS releases Form 1040X. We expect the form to be available in TurboTax in mid to late March. You do not amend until your original return has been processed. When you start your amend, TurboTax will show your refund amount as zero. Then that amount may change as you amend your entries.
When amend is ready, go into TurboTax and follow the instructions for amend. You will delete your dependent in the federal section, then walk through all of the amend questions. Then you can efile your return. When your amend is processed you will be able to efile for your daughter. Her return efile will be rejected until the information is corrected and the IRS no longer has her as your dependent.
You have 3 years from the date you filed your return or 2 years after you paid the tax due (whichever is later) to file an amendment.
