Forms 1099-R report distributions not contributions.
Your basis carried in from 2022 has nothing to do with how TurboTax treats your 2023 traditional IRA contribution. Make sure that you do not tell TurboTax that you "switched" (recharacterized) your traditional IRA contribution. You did a Roth conversion (which is what the Form 1099-R is reporting), not a recharacterization.
