I have two teenage dependents, When I enter the advance child tax credit, it marks the $3,000 I received but will not acknowledge the OTHER $3,000 due to be deducted?

[DanaB27]

Please be aware, when you enter your children and answer some follow-up questions TurboTax adds the full Child Tax Credit to your refund number.  But when you enter the Advanced Child Tax Credit payments, your refund shown will go down because now only the remaining part of the Child Tax Credit is included in the refund instead of the full amount.

You can see your remaining Child Tax Care Credit amount on line 28 of Form 1040. 

To preview your Form 1040:

1. Click on "Tax Tools" in the left menu
2. Click "Tools"
3. Click "View Tax Summary" in the Tool Center window
