This year I realized that the cost basis in form 8606 is incorrect. I had file form 8606 since 2003 but lost the earlier 7 years of them. During a several years I used an accountant and completely mess up the cost basis reporting the end the year value of the traditional IRA account instead of the accumulated non-deductible contributions. Afterwards I used TurboTax, but the software did not ask the question and did not carry over the following contributions. I made the mistake of not educated myself in this subject.
My questions are:
1) Do I have to send the correct 8606 form for every year since 2003 or just need to correct form for the last 3 years?
2) If I need to reconstruct the cost basis, can I request the IRS for the return transcripts of those early years (2003 to 2009)?
Thanks
