IF as parent we paid a Childs full tuition and board for 2019 why is the total amount not reflected soon the 1098 T THEY RECEIVED

The 1098-T does not show payments for room and board. It only shows payments for tuition and fees in box 1. 

For scholarships, grants and out of pocket expenses the only "QUALIFIED" education expenses are books, tuition, and lab fees. That's it. There are no exceptions.

Room and board is not a deductible out of pocket expense, and never has been.
