Concerning advance Child Tax Credit, it asks how much did I receive in advance child tax credit and how much my wife received. Do I input total for me and 0 for my wife?

It has a box for both of us. Do I input the total amount in mine (head of household) and "0" for my wife?

In January you are going to receive a Letter 6419 from the IRS that shows how much -- if any-- advance monthly CTC payments were sent to you.   You and your spouse will each get your own letter with the total you each received.   That will have to be entered on your return and then the amount of CTC still owed to you will be reconciled on your 2021 return.

Did you each get the IRS letter 6419 yet showing how much to enter for each of you ?    Did you two file a joint return last year ?    Are you filing a joint return this year ?
