The Roth conversion was reportable on Form 8606 where the pro-rata calculation results in the entire conversion being nontaxable and the $8,000 of remaining basis (line 14) carrying forward for use in future pro-rata calculations if you make traditional IRA contributions and distributions in 2023 and beyond. Given that you made a contribution for 2022, TurboTax would have left lines 6 through 12 blank and put asterisks on lines 13 and 15 indicating that the pro-rata calculation was done using Worksheet 1-1 from IRS Pub 590-B.
