I need to correct my 2024 federal tax return. I did not put that i can be claimed on my parents taxes and I need to fix that. My parents will be claiming me

Did you already e-file?   If the return was e-filed and accepted, you have to wait until it has been fully processed and then amend your return.  That means the only way your parents can file their return now is by mail.  They will be blocked from e-filing this year with your SSN on their return.  Waiting for you to amend will not help them.

If you have not e-filed, or if your own return was rejected, you can fix this by going to MY INFO to change the way you answered the question that asked if someone else can claim you as a dependent.

If you have NOT filed the 2024 tax return, click on My Info on the left side of the online program screen.  Edit your personal information to change your dependency status.

If you have filed the 2024 tax return then you will need to amend the tax return to change your dependency status.

Before starting to amend the tax return, wait for the tax refund to be received or the taxes due to be paid and processed by the IRS.
