Should I say my dependent's MAGI = $0 during the Affordable Care Act (Form 1095-A) interview question?

My dependent college child made Less than $10K earned income and $2 Dividend Income  so I dont believe she is required to file Federal taxes except to claim a tax refund.

 

During the interview for the Affordable Care Act (Form 1095-A) Turbotax  asks "What's your child's modified adjusted gross income (MAGI)?" 

 

There is a big difference in the Premium Tax Credit depending how I answer this.

 

Since she is not required to file Federal taxes (Except fot the refund) Should I answer the question by saying MAGI = 0?
