Does my dependent daughter need to file with ssa 1099 benefits of $9,255 and no other income at age 7?

She is not a survivor nor disabled. Her benefits come from me being retired. Most of the answers that I read here say if that is her only income, then no, she doesn't. (If I'm reading them correctly). However, other sites say that:"•For single dependents who are under the age of 65 and not blind, you generally must file a federal income tax return if your unearned income (such as from dividends or interest) was more than $1,050 or if your earned income (such as from wages or salary) was more than $6,300.  So, is ssa unearned income for her? I obviously claim her as a dependent.  I'm so confused.
