For supported situations, you can trigger Form 8606:
- Continue working on your return in TurboTax OnLiine. (If your return isn't open, you'll need to sign in and click Take me to my return.)
- Click Tax Tools (lower left of your screen).
- Select Tools.
- In the pop-up window, select Topic Search.
- In the I'm looking for: box, type 8606.
- In the results box, scroll down and highlight 8606, nondeductible ira contributions, then click GO.
- Proceed through the IRA interview answering questions as you go.
- When you reach Any Nondeductible Contributions to Your IRA? check Yes, I made and tracked nondeductible contributions to my IRA and click Continue.
- Continue following the onscreen instructions.
Note: If using the TurboTax CD/Download software, you'll use the Find function and the "Jump to" link (instead of "Tax Tools") to search for the topic.
