2024 1099 interest ( $420) from 2022 federal refund has decedent social security number .What should I do ?

I am the executor of my son's estate. I received a 2024 1099int in care of me with his social security number. The interest amount is $420 on the refund from his 2022 1040 there is no other income in 2024. The" Final" 1041 and estate tax forms were filled in 2023. Can I just add the interest to my return ?

Or do I have to file an additional estate return(even though the 2023 filing was identified as "final") and K1 the interest to me ?

Or I have to file a form 1096 using his social security number and move the interest to me ?

Appreciate any help. Thanks in advance.
