If you received a form 1098-T, you must include it in your tax return. You must include all tax forms you receive in your tax return.

To enter your 1098-T, click on "Federal Taxes" > "Deductions & Credits" > scroll down to "Education" and click start next to "Expenses and Scholarships (Form 1098-T). 

You may still get the education credit, but by going through the program, TurboTax will guide you and let you know if you do qualify for the education credit.
