Deductions & credits

So the Additional Child tax credit line  in turbo tax shows how much we received in 2021 for advanced payments. Why is turbo tax not showing the total credit amount given in the program? Which in turn is over $5148.00 in child tax credit. (So if we received advanced payments in 2021 of $2577, Turbo tax will only give credit for the other half which reflects on Additional child tax credit line? Then that leaves the child tax credit line blank with $0 dollars. Does that sound correct ?
