DECEASED FATHER'S 1099-R MILITARY ARREARS PAY MADE OUT IN MY NAME/SOCIAL SECURITY NUMBER
My father was retired military with a pension. He passed away in 2019 and I'm trying to do his final return for his federal taxes for the year 2019.
Last week, I received a check from DFAS (handles military pensions and pay) make out in my name with the wordage "A/C <my fathers name> RET/DEC". The check hasn't been deposited. The same day, I received a 1099-R form with the recipient listed as myself and the same notation on the check. It also had my social security number listed on the 1099-R form, the 'distribution code' on this form shows '4', and the notes on the form state 'ARREARS" (I also have an additional 1099-R for 2019 which appears to be for his pay from last year).
I have a brother who was in my father's will (I'm the court-appointed Estate Administrator). Initially, I assumed I'd cash the arrears check into my father's 'estate' account so that it would be split between my brother and myself and that the 'arrears' 1099-R form would be filed under my dad's income from 2019. However, as the form has my name and Social Security Number, it appear that I'm personally being taxed for this income. I already filed my own taxes about two weeks ago (the e-filing was accepted by the IRS).
A link to 'arrears' at DFAS is given here: https://www.dfas.mil/retiredmilitary/provide/aop.html
My questions are:
1) Is the second 1099-R (for arrears) meant for my own taxes and not my father's? If yes, is the check meant solely for me as I'm being taxed for it (or did DFAS make an error)? Also, if yes, how do I/what form would I need to file to amend my own taxes which have already been submitted to the IRS?
Please advise and thanks.
