Filing 2022 taxes for taxpayer who passed away in 2021

My mother passed away on Dec. 23, 2021.  I filed her federal and state income taxes in 2022.  In March, 2022, she received a dividend on some stocks she owned, before these stocks had been reissued to her heirs.  That was the only income she received in 2022.  I thought I should file a 2022 return documenting this income.  Turbotax will not allow me to enter 12/23/2021 as the date of her death, insisting the date must be in 2022.

 

Do I need to file a 2022 tax return in order to account for the dividend ($1,300) she received in that tax year?  If so, how do I get around the problem of answering the data-of-death question?

 

Thanks.
