The tuition deduction reduces your taxable income, which means it does not give you an additional refund, it just reduces the amount of income you are taxed on by the IRS. It may be that the amount of the tuition deduction received for this form did not reduce your income enough to give you an extra refund amount.

Other factors such as whether or not you qualified for the deduction or if your deduction was limited could affect the credit as well. More information about this credit can be found here: https://www.irs.gov/publications/p970/ch06.html#en_US_2016_publink100025391
