I assisted my 18 year old granddaughter to file her 2020 tax return to get EIP 1 and EIP 2. We checked No to "Can someone (such as your parent) claim you as a dependent". She received her refund.
Her mother wants to claim her daughter for purposes a court cash with X husband. How do I amend the granddaughter's tax return to say she can be claimed and return the EIP payments?
