Seems everyone's 8606 issues are special. I've properly filed the 8606 each year required but with the wrong Basis, like so many others. There is no change in any non-deductible contribution for any years from 2004 to 2015 to be corrected on the 8606. Made no contributions, deductible or non-deductible since 2015. No distributions have ever been made. So, all those old form8606 are on "closed" tax returns. Already filed my 2020 Tax return and it has been accepted. Wanted to amend my return and add a 8606 with "0" contribution with the corrected Basis for 2020. Shouldn't I just send a tax year 2020 form 8606 alone to the IRS with a written notice "this is corrected Basis from last filed 8606 in 2015"? Can I send it with my spouses, since both have the wrong Basis, since there isn't any over or under payment of taxes for any year? I want to get the basis correct this year as I'm planning some recharacterization of the non-deductible portion to a Roth IRA. I just realized the Basis error this past month.
TurboTax doesn't have the 1040X ready at this time. If needed, when will TT have the 1040X form? there will be no changes on any line of the 1040X.
What is the simplest way to do this? I have all past years 8606 with corrected Basis but worry about sending too much detail to the IRS. Some posts just state to send the current year 8606 with that explanation.
