I know the amount of my advance child tax credit. I am married, filing jointly and it's asking for my credit as well as my spouse. Do I just enter mine or both?

We got half of the child tax credit, $250 a month for 6 months. $1500 total. I can't enter $1500 on my line and my spouse because that will make it $3000. $750 on each line? $1500 on just one?
