Income Tax Due

My daughter is a college student in graduate school.  She is less than half-time because the courses are difficult and outside her undergraduate degree course of study.  In 2019 she volunteered with a non-profit equine adaptive therapy facility.  At the middle of the summer, they asked her to help feed the 13 horses and paid he as a 1099 worker (No issues here - no taxes withheld).  Total wages earned are $1200.00 - she has no other source of income for now.   She lives with my wife and I to share expenses helping her through school.

 

Working through TurboTax the amount of tax due is $87.00.  For not-married filing single, with a $12,200 standard deduction, I am not understanding taxes on the small income.  Also the over $4200 for her individual health insurance, the $2600.00 for tuition, books, and supplies, seem to have no effect due to the standard deduction.  

 

Thoughts and recommendations from the community?  Am I missing an area of opportunity?
