I need to print the schedule 8812 used for my 2021 tax return for a 1040X. How can I print just this form.

It depends on which program you are using, desktop or online.   

You can print ALL the forms, schedules, and worksheets for your return in TurboTax Desktop by following these steps:

1. Open your return
2. Click "Print Center" in the upper right-hand corner of your screen
3. Choose "Forms to Review or Keep for your Records" 
4. From here you can choose to print your return and ALL of your worksheets

In TurboTax online follows these steps:

If your return is still open, you can click on Tax Tools (left-hand side of the screen), and then Print Center.

If you have already printed and filed, these are directions to Print Center:

1. Log back into your account (if not already open).
2. Click on Tax Home (left-hand side).
3. Scroll down to Your tax returns & documents and click on Show
4. Click on Add a State to get back in return.
5. . In the left-hand menu, Click on Tax Tools.
6. Select Print Center.
7. Then choose Print, save or preview this year’s return.
8. Now check the 2021 federal returns (or 2021 state returns) box and choose which forms to print out or all worksheets.
9. Select View or print forms, then go ahead and print.

Please Note: If you correct something after a reject or amend the return, it works better to print from Print Center.
