fanfare is correct. The final tax return for a decedent dying in 2024 is the 2024 tax return if there is any income earned in 2024 before death, as is the case here.
The notice at the top of the Form 1040 does not necessarily imply a final tax return. It informs the IRS that someone other than the decedent has signed the tax return and any refund is to be paid to the appropriate recipient, perhaps the decedent's estate, not to the decedent.
