The nondeductible contribution for the 2022 should have been reported on your 2022 return. You should have a 2022 Form 8606 with a basis on line 14. You will enter this basis in your 2023 tax return when TurboTax asks "Any nondeductible Contributions to your IRA?".
Please review How do I enter a backdoor Roth IRA conversion? and see "If your conversion contains contributions made in 2023 for 2022"
