Another thing....are you and your spouse living together or have you lived apart for at least the last six months of 2020? If that is the situation---then you have a whole different set of issues. The "uncooperative" spouse could file as Head of Household if that spouse has the kids. HOH can get all of the child-related credits----is that what is going on? The rules are not the same for HOH. One of you could file HOH and the other would have to file MFS.
And... no matter how you file----you cannot both claim the same child(ren) if you file separate returns. The SSN of a child can only be used on ONE tax return.
You might want to consider going to a paid tax pro in your area to get it all clarified.
