The IRS instructions for Box 5 are:
"A scholarship or grant is administered and processed by you if you receive payment of an amount, whether by check, cash, electronic transfer, or other means, and such payment is designated as a grant or a scholarship by the payor, or the circumstances make it clear that the payment is a grant or scholarship. A Pell Grant is an example of a grant administered and processed by a college or university in all cases."
Therefore if you received a W-2 that has amounts designated for your education "ONLY" and these represent amounts that the college or university is reporting on your W-2 (for example reimbursement for course work that you completed and paid out of your own funds that your employer had previously reimbursed you for, those amounts MAY appear on your W-2 and thus TurboTax needs to know what those amounts are so you do NOT count the income twice (and thereby increase the amount of tax that you will need to pay).
Hope that helps
