First, you will have to wait until the IRS either accepts or rejects your return -- the IRS will not even begin processing returns until January 23, so you have a few weeks to wait. Meanwhile, do NOT try to change anything on your return or you will make the problem worse.
So did you file a return that said no one else could claim you as a dependent and now your parent's return is being rejected? But really you can be claimed as their dependent?
Your parents will have to prepare their return that claims you as a dependent and MAIL it to the IRS. They cannot e-file now. But they can go ahead and do that without waiting for you to amend your return.
Your part of fixing this is to file an amended return. You have to change the answer you gave in Personal Info when you were asked if you can be claimed on someone else’s tax return. Wait until your return has been fully processed and you have received your refund.
The form you will need to prepare an amended return is called a 1040X, which becomes available sometime in February. You amend to say in Personal Info that you can be claimed as someone else's dependent. Then you print and mail your 1040X. It will then take 2-4 months for the IRS to process your amended return.
