@Hi9cke1234 Your return is being rejected because she filed her tax return and did NOT indicate on her return that she can be claimed as a dependent. She needs to amend her 2021 return and change her dependency status if you file your return with her as your dependent.
See this TurboTax support FAQ for amending a 2021 return - https://ttlc.intuit.com/community/tax-return/help/how-do-i-amend-my-2021-return/00/2544441
You will not be able to e-file your tax return since the IRS has already received a tax return with her Social Security number as a tax payer and not a dependent.
So, you have two choices.
1. Remove her as a dependent on your tax return and e-file. This option deprives you of the $500 Other Dependent tax credit.
2. File your tax return with her as your dependent but it will have to be printed and mailed. The IRS will pay you any tax refund from your mailed tax return.
