No, if your employer reimbursed you for your education expenses and did not include it on your W-2 you cannot take a deduction for this.
If, on the other hand, the reimbursement was included in box 1 of your W-2, then yes, you would be able to enter the 1098-T.
Generally, when the 1098-T is showing more than you were actually billed, it is including tuition for the following year. You would see a check mark in the box regarding amounts due include spring or Jan-March.
