Because your Roth conversion is occurring in calendar year 2026, you do not need to wait for a 1099-R or file an extension for your 2025 return.
To ensure your 2025 contribution is correctly marked as non-deductible and generates Form 8606, follow these steps in TurboTax:
- Enter the Contribution:
- Go to Federal > Deductions & Credits.
- Find Retirement and Investments and select Traditional and Roth IRA Contributions.
- Check the box for Traditional IRA.
- Confirm the Amount:
- Answer Yes that you made a contribution.
- Enter the exact amount you contributed (e.g., $7,000).
- Indicate it's Non-Deductible:
- TurboTax will ask if you "tracked your basis" or if you want to make this a non-deductible contribution. Select Yes.
- On the screen titled "Tell Us How Much You Contributed," confirm the amount is listed under the "Traditional IRA" column.
- Verify Form 8606:
- Before you file, use the Tax Tools > Tools > View Tax Summary > Preview my 1040 method mentioned earlier.
- Look for Form 8606. Your contribution should appear on Line 1, and your total basis (which will carry over to next year's conversion) should be on Line 14.
Important: Since your conversion happens on 4/14/2026, do not enter any conversion information in the 2025 return. You only report the $7,000 contribution.
