With regard to IRA contributions, Form 8606 only reports nondeductible contributions. A deductible contribution is instead reported on Schedule 1 line 20.
Form 8606 is to be included in the tax return for an individual only if the individual has made a nondeductible traditional IRA contribution for the year, made a traditional IRA distribution (other than a Qualified Charitable Distribution or HSA Funding Distribution) when the individual has basis in nondeductible traditional IRA contributions, performed a Roth conversion or received a nonqualified distribution from a Roth IRA. If one of these requirements is met, TurboTax will include that individual's Form 8606. If none of these was done in 2023 TurboTax will properly exclude Form 8606.
If Schedule 1 line 20 is blank and Form 8606 is not preset, it implies that you have not entered a traditional IRA contribution for that individual.
