$1,400 Recovery Rebate Credit

[RWG1950]

My elderly (100 years old) customer died on 6-15-21.
Her 2020 AGI was more than 90K, so she was not provided with the $ 1,400 recovery rebate credit in March of 2021.
Her final return (2021) has an AGI of $ 42K & my software wants to give her the $ 1,400 she hadn't received.
Anyone know of a reason why she (or her estate) would not be entitled to claim the credit ?
Thanks for comments

If a person died in 2021 or 2022 and didn't get the check they were eligible for then they qualify for the recovery rebate. They simply need to have met eligibility requirements while they were alive. If someone died prior to Jan. 1, 2021 they will not qualify for the recovery rebate credit.
