I shared an investment account with a relative who died in 2023. I was also the executor of the estate and filed a final tax return for the year 2023 for the relative. However their was an investment account we held as joint tenants in common along with another relative. The investment firm didn't close that account and divide the proceeds until mid-2024 and has now created a 1099 for the dividends and interest that came into the account before the proceeds were dispersed. The 1099 is in the name and social security number of the decedent.
Since a final tax return has already been submitted for the decedent, how do I report the 1099-int and 1099-div on that account?
