Continue your return in TurboTax Online. (If your return isn't open, you'll need to sign in and click Take me to my return.)
Click Tax Tools (lower left side of your screen).
Underneath Tax Tools, click Tools.
In the Tools Center popup window, click Topic Search.
In the I'm looking for: box, type 8862.
In the results box, highlight 8862, then click GO.
This should take you to the EIC interview. Follow the onscreen instructions to advance through the interview. When TurboTax prompts "Do any of these uncommon situations apply?", check "I got a letter/notice from the IRS telling me to fill out an 8862 form to claim the Earned Income Credit" and click Continue.
Continue through the interview. On the screen that says "Since you got an IRS notice, we need to check on a few things", select "No, none of these apply and I need to fill out the 8862" and click Continue.
Continue following the onscreen instructions to prepare the Form 8862.
