After you file

Your post is unclear.   If your parent claimed you as a dependent and already e-filed, then if you say on your own return that no one else can claim you as a dependent, your own e-file will be rejected.  

So.....we need to determine if your mom can claim you.  If she can claim you, you must change your answer in MY INFO to say that someone else can claim you as a dependent, and then you can try again to e-file.

Here is the criteria your mother needs to use:

WHO CAN I CLAIM AS A DEPENDENT?

You can claim a child, relative, friend, or fiancé (etc.) as a dependent on your 2024 tax return as long as they meet the following requirements:

Qualifying child

• They're related to you.
• They aren't claimed as a dependent by someone else.
• They're a U.S. citizen, resident alien, national, or a Canadian or Mexican resident.
• They aren’t filing a joint return with their spouse.
• They're under the age of 19 (or 24 for full-time students).
• No age limit for permanently and totally disabled children.
• They lived with you for more than half the year (exceptions apply).
• They didn't provide more than half of their own support for the year.

Qualifying relative

• They don't have to be related to you (despite the name).
• They aren't claimed as a dependent by someone else.
• They're a U.S. citizen, resident alien, national, or a Canadian or Mexican resident.
• They aren’t filing a joint return with their spouse.
• They lived with you the entire year (exceptions apply).
• They made less than $5050 in 2024.   (Not counting Social Security)
• You provided more than half of their financial support.

When you add someone as a dependent, we'll ask a series of questions to make sure you can claim them. There may be other tax benefits you can get when you claim a dependent.

If your mother is the one who made a mistake and should not have claimed you, then Mom will need to amend her own return after it has been fully processed.   If you cannot be claimed, you can say no one can claim you but you will now have to file by mail.  You cannot e-file this year.  Print, sign and date your return in ink, and mail it in.   Waiting for Mom to amend will not help you to e-file.

When you mail a tax return, you need to attach any documents showing tax withheld, such as your W-2’s or any 1099’s.  Use a mailing service that will track it, such as certified mail so you will know the IRS/state received the return.

Federal and state returns must be in separate envelopes and they are mailed to different addresses.  Read the mailing instructions that print with your tax return carefully so you mail them to the right addresses.
