TurboTax is adding $1800 stimulus credit on Final return for grandma who passed away before stimulus date

Grandma was one of the first who passed away during the pandemic in March — just before the first stimulus, so she was not entitled. She actually received $1200 but we mailed it back to the IRS. No problem. But now that we’re filing her final return, even though we entered her date of death (which makes her ineligible), TurboTax is adding $1800 in stimulus to her refund. How do we override this?  Thank you.
