Where is employer pay recorded on a student's 1098-T?

Is an employer's third-party payment made directly to the school reportable in box 1 or box 5 of the 1098-T? I have read that many schools will report it in box 5 but I have also read that it should not be reported in this box. Does it change if the school and employer have an agreement/cohort established? Is the reporting affected by the max amount of $5250 for employer tuition benefit?
