Schedule 8812: Advance payments received must be entered? / Principal Place of Abode and Letter 6416 Information Smart Worksheet

My Spouse and I received $1400 each of the Economic Impact payments. Now the question is I'm doing my taxes on TurboTax and it keeps telling me I have to fill out the part the Schedule 8812, advance payments received must be entered. When I enter the $2800 it lowers my refund. We received a letter from IRS stating that the Impact payment is not considered taxable income. We don't have any kids so do I just zero amount for the child tax credit payments.
