Do I have to file taxes if I only earned $1500? I filed and owed taxes on this. I'm a minor & dependent.

I only earned $1500 lst year as a student (I'm a dependent, living home with my parents) from an internship.  The employer did not take any taxes out and gave me a 1099 NEC.  I filed and owed about $250.  Does this sound right?  I just found out that under about $12,500 income, you don't even need to file taxes.
