My child made less then 6000 dollars. I am claiming her on my tax return as a dependent. Does my child need to file a tax return?

unearned income was over $1,050
earned income was over $6,300, or
earned and unearned income together total more than the larger of (1) $1,050, or (2) total earned income (up to $6,300) plus $350.
