Tax year 2022 was my first year for traditional IRA contribution, and in the same year (around March 2022), I did a full conversion to a Roth IRA (backdoor Roth IRA). Thus from April 2022 through December 2023 my Traditional IRA balance was $0. In January 2024, I made traditional IRA contributions for tax years 2023 and 2024, and I also converted both into Roth IRA (backdoor) within a week. I never received a 1099R for 2023. In January 2025, I received a 1099R listing the tax year 2023 and 2024 contributions.
1) For which tax years should I submit Form 8606?
2) If both 2023 and 2024 contributions will be on the same tax year 2024 Form 8606, where in Parts I and II do I list just the tax year 2023 amount, just the tax year 2024 amount, and the total amount contributed/converted in January 2024 for the combined 2023 and 2024 tax years?
3) What other year forms or fields should be filled or adjusted?
