First, revisit the My Info section to verify your dependent's Social Security number (if it was entered incorrectly, correct it and go through the File section to resubmit your return).
Note: If your TurboTax navigation looks different from what’s described here, learn more.
If you already verified this info, you'll need to paper-file your return, as the IRS will continue to reject your attempts to e-file.
Then, if you know who claimed your dependent, ask them to amend their return by removing the dependent. Amendment processing can take weeks or even months, which is why it's best to paper-file your return in the meantime.
If the other taxpayer is uncooperative, the IRS will eventually contact both of you to figure out who gets to claim the dependent. The losing party will then be liable for any additional taxes, penalties, and/or interest as a result of the false claim.
Important: If you don't know who might have claimed your dependent, it could be a case of tax-related identity theft. Please contact us for assistance. What to do if you suspect identity theft.
