Your daughter can still be on your health insurance until she is 26. That has nothing to do with being claimed as a dependent on a tax return. She is too old and had too much income to be claimed as anyone else's dependent. She can file her own tax return to seek a refund of tax withheld. She cannot be claimed as a dependent for tax year 2025.
