You made a very common mistake that will now make it impossible for the person/people who can claim you to e-file this year. They have to file by mail now.
Did you e-file first——and now is your parent’s return that claims you as a dependent being rejected when they try to e-file?
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 processes 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.
When your own return has been fully processed, you will have to amend it. When you amend you will go to My Info. Click your name and go through the screens to the question that asks if you can be claimed as someone else's dependent. You need to say YES. Do not amend yet. Wait for the IRS to process your return. Your parent does not need to wait for you to amend. They can mail her return whenever they are ready. Waiting will not help them.
