What if box 1 is blank on my student's 1098-T? Should I use the amount from the tuition bill we paid or call the school to revise the 1098-T?

she had a scholarship reported in box 5, but no tuition in box 1... so it looks like we have to pay tax on the scholarship.  But the tuition statement we have shows the amount of her tuition, the amount of the scholarship and the amount of the check that we wrote.  Should I just enter what I think the correct amount is for box 1?  Or call the school again?  they were no help after my first call.
