I tried to trigger a Form 8606 because a tax expert told me I'd need to submit it every year we had a basis. (She had me mail in thirteen 8606's for the years between the creation of the IRA and the 2020 conversion year.) In 2020 we converted a portion of the traditional IRA to Roth IRA and TurboTax created an 8606 to reflect the amount that was not taxable (old combat pay rolled into the IRA long ago). In 2021 we neither contributed nor converted any amount from the IRA. Should TurboTax have created a 2021 Form 8606? I tried to trigger it as noted here in the Community. If it should not have because we didn't touch the IRAs in 2021, do I just keep the 2020 Form 8606 and update from that the next time we convert the IRA with no 8606 forms for the years in between? Or do I need to file Form 8606 for every year we have a basis even if we've had no new activity during that year?
