Missed filing form 8606 for 2022 to 2025
I did NOT know that I am required to file form 8606 for each year that I did 72T distributions. I just found out yesterday, that a non-deductible contribution to a Traditional IRA that I did in 2008 has major impact on the 72T distributions that I started and got in 2022 to 2025, and this year 2026 (though this is not an issue since this income is yet to be filed next year)
Please advise as to what should I do to correct my 2022 to 2025 tax returns. Do I need to file amended returns for each year 2022 to 2025? If amended returns are needed, can I go back to my Turbo Tax software in 2022 to 2025 and do the corrections using the turbo tax? Or can I just figure out the basis for each year and just file the related forms 8606 for each year missed?
I would greatly need your expert advise on this. Thank you!
