I filed the parents joint return timely last year and marked boxes indicating that they can be and are being claimed as dependents. They only had social security income but wanted to file just for the record.

It is now that we are trying to file the daughters tax return claiming them as dependents but efile rejects because ss numbers indicate parents filed joint return but apparently not recognizing the "can be claimed" markings.

Hoping there is some place on daughter's return that I can indicate that parents did not claim themselves.

Trying to avoid filing manually since daughter has large refund due.
