My wife died in May of 2020. In 2021 a $300.00 death benefit was issued to me, and I'm trying to enter it in Turbo Tax. TurboTax is asking which year it is "for." ???

I tried to enter 2021, the date the additional IRA amount of $300.00, and the Turbo Tax system says, "cannot exceed 2020."  Where do I enter the $300.00???
