You do not get a refund from TurboTax for filing your tax return. You just need to fix it and re-file, and give the correct answer in My Info to the question that asked if you can be claimed as someone else's dependent.
CAN I FILE A RETURN IF I AM A DEPENDENT?
If you can be claimed as a dependent on your parents’ return, you can still file your own return so that you can receive a refund of taxes withheld. (You will not get back anything for Social Security or Medicare withheld.) Be sure that on your own return you say that you can be claimed as a dependent on someone else’s return.
