When entering the code-2 2023 Form 1099-R into 2023 TurboTax, indicate that you moved the money to another retirement account and that you converted the entire amount to Roth.
If you have already started your 2023 tax return in TurboTax, be sure to click the Continue button on the page that lists the Forms 1099-R that you have entered, indicate that you made nondeductible contributions to your traditional IRAs, then enter the amount from line 14 of your 2022 Form 8606 that you will be filing as an amendment to your 2022 tax return.
No entries are made directly on Form 8606. TurboTax prepares Form 8606 automatically based on your entries elsewhere as I have described.
