Self employed student has 1099-misc for $10,000, but Turborax I need to pay taxes on full amount

I am a student, self employed, and claimed as a dependent by my parents. My 1099 for the year is  $10,243. I thought as a student under $12,200, I do not have to pay taxes. Yet Turbo Tax says I owe approx. $2,500 in federal. Please help, that does not appear to be correct. I am using TurboTax Home and Business. Thanks
