TurboTax is doing it right. The standard deduction for a person, who CAN be claimed as a dependent, is $1,250 or your earned income plus $400, whichever is greater (but not more than $13,850).
So, it's possible for dependents with earned income to get the full $13,850 standard deduction. Those with only unearned income only get a $1250 standard deduction. As noted in previous comments, on this thread, you get the same standard deduction whether your parents actually claim you or not. It's the fact that you qualify as a dependent that restricts your standard deduction, not whether you are actually claimed as a dependent.
