After you enter your Form 1099-R, continue past the "Review your 1099-R info" page. You will be asked a series of questions. Go through the questions until you see "Enter Prior Year IRA Contributions". Enter Roth IRA contributions made prior to 2024. This will add them to Form 8606, and result in your Roth IRA distribution being non-taxable. Note: If your Roth IRA was not open for at least five years, your withdrawal, although not taxable, will be subject to a 10% penalty (excise tax) for early withdrawal.
