Your parents cannot e-file this year---at all, When you filed a tax return that said no one could claim you as a dependent you put your SSN into the system and it will stay that way for many months even after you amend, No one else can e-file a tax return with your SSN on it, so now the only way your parents can file their tax return is by mail. The IRS processed mailed returns a different way, so the duplicate use of your SSN will not stop the IRS from processing your parents' mailed return. The problem is that it takes the IRS a lot longer to process mailed returns, so if your parents need their refund they will wait a lot longer for it.
If it is any comfort, you (and your parents) are among many young tax filers who make this mistake. We will be seeing plenty of posts just like yours. And posts from the parents whose e-files were rejected....
