Did you already e-file? Is that mistake blocking your parent--or someone else who can claim you--from e-filing now? You have to wait for your return to be fully processed. Then you can amend. You will need to go to My Info, click your name and go through the screens to the question that asked if you can be claimed as someone else's dependent. Change your answer to YES.

Meanwhile...if there is someone whose e-file is being rejected-----they have no choice this year but to file by mail. Waiting for you to amend will not help them. You can be claimed on their return but they cannot e-file. Your SSN is in the system and no one else can e-file a return using your SSN this year. They need to print, sign and date their return in ink and mail it in.
