How do I choose the spouse who claims the DTC?

Hi We tried all these spouse is not listed as dependent the issue is the credit for DTC and caregiver credit are not showing on any of us return even we answered the questions correctly. Like I mentioned before if you look at the call log I have spent twice 1h30 mins and couldn’t resolve the issue and that to repeat same process without any solution each time and was promised a call back for a solution to this issue unfortunately no one did.
