Form 8615 (the "kiddie tax") applies to fulltime students, under 24. "I worked at the end of 2022" seems to infer that your were a FT student for parts of 5 calendar months in 2022. You are not subject to the kiddie tax if more than half your support, for 2022, came from your own earned (working) income.
