You get the full Child tax credit ($3000 per child, $3600 for children under 6), but the amount you got, in advance is subtracted, on Schedule 8812, before the net amount is entered on lines 19 and 28 of form 1040.

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:
   • Select Print Center and then Print, Save, or Preview This Year's Return to preview your entire return, including all forms and worksheets (you may be asked to register or pay first).
   • View only your 1040 form by selecting Tools. Next, select View Tax Summary in the pop-up, then Preview my 1040 in the left menu.
