Hi there-
Did you already file your returns and were they accepted? If so you will need to file an amended return for both the FED and the State. You need to indicate that you were claimed as a dependent on another return. You will find this in the 'Your Info' section where you entered your name. First indicate that you need to file an amended return, then go in and select that you will be claimed. TurboTax will then prepare all of the amended forms for you to sign and mail in with any payment that may be due. Let us know if you have any additional questions.
