1099-INT for deceased mother

 

My mother died in 2022..

 

I was payable-on-death beneficiary of her bank account.

 

All funds were withdrawn from bank in Oct 2022.

 

1099-INT with her Social Security number shows interest for 2022 was $87.

 

$10 of interest was credited after she died.

 

My understanding is that $77 is taxable to my mother.

 

$10 is known as “income in respect of a decedent” and is taxable to me.

 

QUESTIONS:

 

(1)  If I add $77 to her return and $10 to my return, the amounts won’t match the 1099-INT information received by IRS for each of us.  Do I need to send two letters to IRS explaining why the numbers on each return don’t match the information received by IRS ? How do I send the letters if I file returns using TurboTax?

 

(2)  For simplicity, would it be OK to add the entire $87 in interest to my mother's return because the 1099-INT shows only her Social Security number?
