The 2024 Form 1099-R will have code P, not code 8. Since there is no tax withholding, the result would be the same if you enter a 2023 Form 1099-R with code 8, but entering it as a 2024 Form 1099-R with code P would be more accurate for recordkeeping. When entering a code-P Form 1099-R into 2023 TurboTax, TurboTax will ask if its a 2023 form or a 2024 form, so you need to answer that it's a 2024 form.
