Unemployed for the Year and opened a CD

I took the year off from work starting from late December of last year (2022). I just wanted time off as I felt completely burned out. I wanted to rest, but also do personal things I held off from doing. Anyway, do I need to file taxes despite not working at all? Also, I updated my bank accounts, including opening a Timed Account, or a CD. Do I need to file for that?
