The form 1040 and the rest ... don't stop at the summary screens since they can be misleading and/or confusing. 

How do I preview my TurboTax Online return before filing?

You can view your entire return or just your 1040 form before you e-file:

1. Open or continue your return.
2. Select Tax Tools in the left menu (if you don't see this, select the menu icon in the upper-left corner).
3. With the Tax Tools menu open, you can then:
• Preview your entire return: Select Print Center and then Print, Save, or Preview This Year's Return (you may be asked to register or pay first).
• View only your 1040 form: Select Tools. Next, select View Tax Summary in the pop-up, then Preview my 1040 in the left menu.
