When completing my 2022 return I discovered that I missed line 76 on my 2021 return (spouse credit). I want to fix that but can't fund section on refile. Please help

Can I use that and Caregiver amount? Because I claimed that for my spouse but the credit is larger for line 76.  I ended up owing for the first time in 2021 since I was married and I wondered why.  I believe I found the issue.
