My mother-in-law died in December of 2021. She had already taken her 2021 RMD. Due to timing of her death, it was 2022 before my wife and her sister liquidated the account. TT is asking me what portion if any of the withdrawal is an RMD. I believe none of it was as she was already deceased and therefore not required to make an RMD for 2022, obviously. But what should I tell TT; "all of it was an RMD", "none of it was", or do I calculate what it would have been? I'm confused as to why a lump sum total distribution for a deceased person's account is even being asked.
