Dependent received 2021 refund check in mail for Earned Income Credit?

My 19 year old daughter recevied a check out of nowhere from the IRS for $1,209 stating "we made the changes you requested to your 2021 Form 1040 to adjust your earned income credit".  I filed my taxes for my daughter using TT online.  I confirmed that the return stated that she is a dependent on someone else's return (mine) and did not claim the EIC.   I never requested any changes.  Am I missing something?   Will this get adjusted somehow when she does her 2022 taxes?
