You are correct, the basis withdrawal isn't taxable. You will need to input the basis- without an entry, there is no way to determine the basis.
Here is how to navigate TurboTax Online to report your ROTH basis:
- Navigate to Traditional IRA and Roth IRA Contributions in the Deductions and Credits section.
- On the Tell us about your IRAs screen, check the Roth IRA box and select Continue.
- Continue through the interview to enter your current year (2025) contributions on the screen that asks you to Enter your regular Roth IRA contributions.
- Continue through the interview, answer Yes to the question Did you open any Roth IRAs in 2024 or any previous year?
- Answer Yes to the question Do you want to track your Roth IRA basis?, and proceed to report your basis.
