TurboTax will not let me enter info in Expenses and Scholarships (Form 1098-T) to get the American Opportunity Tax Credit. I meet qualifications. Ideas?

I entered a 1099-Q Form for Qualified Education Programs. Now, program says I don't qualify for the American Opportunity Tax Credit and won't let me enter any education expenses which are more than the 529 plan I cashed and paid for daughter's education.
