1099-MISC summer internship

My daughter got a 1099-MISC for a summer internship for $4300 and she also has a W2 for $1800. After entering the 1099-MISC information I get different results based on how I answer the question about intent to earn money.  If I answer "No", then TurboTax says calculates no Federal Tax, and if Yes then there is a federal tax of $608 and I have to fill the schedule C.  All the online places I checked say to answer "No" to the intent question.  Can I get some clarity on this option
