Why Does TT Require Form 8615?

I entered a $4800 research stipend in "Other Scholarships/Grants/Fellowships" via "Scholarships/Grants (for all schools)".  All of it was used for room and board and I entered it as such.

 

As soon as I did so, TT began requiring a Form 8615. But IRS Pub 501 clearly states, "Earned income includes wages, salaries, tips, professional fees, and other compensation received for personal services you performed. It also includes any taxable scholarship or fellowship grant."

 

  1. Why is TT requiring the 8615 for a taxable stipend?
  2. Where else should I enter that $4800 so it will be treated as earned income for kiddie tax purposes?
