If your Scholarship in Box 5 is exactly equal to your Tuition in Box 1 of Form 1098-T, TurboTax may be electing to use $4,000 of your tuition to make you eligible for the American Opportunity Credit.
If this is the case, that $4,000 of tuition cannot be used as a qualifying expense for your scholarship and that scholarship gets added to your taxable income. However, if you had other expenses that the scholarship could cover besides tuition, then you can add those within the Form 1098-T screens. These expenses can include books and supplies. Other uses of the scholarship lead to it being considered taxable income, and you may have to fill out Form 8615.
Please note that the requirement to file Form 8615 suggests you are eligible to be claimed as a dependent. Generally, it is the parents who include Form 1098-T on their tax return, with the sole exception being if you are eligible for the American Opportunity Credit but your parents' income makes them ineligible to claim it. In that case, you may claim it on your own return but your parents can't claim you on theirs.
Although you may have to pay taxes on a portion of your scholarship income, claiming the American Opportunity Credit will yield a better tax outcome than not taxing your scholarship and not claiming the credit.
