Q. How do I reflect the amounts reimbursed and not reimbursed?
A. After entering your 1098-T, in TurboTax (TT), you will be asked if you had any tax free employer reimbursement. Enter the amount your were reimbursed. TT will use the difference to calculate a tuition credit.
Your employer may reimburse you, tax free, for tuition, up to $5250. So the reimbursement is only entered to reduce the amount of tuition eligible for the education credit.
