Confusion about stimulus payments to dead people.

My wife passed away in January 2020. In March 2020 I received two $1200 stimulus payments, one for myself and one for my deceased wife. In January 2021 I received the second stimulus payment of $600 for myself but not for my wife. TurboTax is giving me a $600 credit for my deceased wife’s second stimulus payment.

I’ve read various reports that dead people are not eligible for the stimulus payment and that it should be returned to the IRS if paid.

Does anyone have a definitive answer as to whether dead people are eligible to receive the stimulus payment?
