As I said, the tax software all treated the scholarships as earned income for the purpose of the standard deduction for my daughter for the last 4 years. She got the ~$6400 as a standard deduction and for at least 2 of those years, her only income was the scholarships. In all 4 years, her unearned scholarship income was much higher than her earned income, and she always got the full standard deduction.
