Incorrect amount being using "for credit or deduction" on Student Worksheet?

I'm claiming the American Opportunity credit this year (not the lifetime learning credit).  TurboTax is putting $10,000 on line 17 of the Student Worksheet (amount of the qualified educational expenses used for credits and/or deductions).  I thought that the American Opportunity credit uses only $4,000 of the qualified educational expenses and am trying to figure out how to correct it.  An incorrect value has impact on the amount my daughter should report as income on her tax forms.
