So I attended college the Spring semester of 2016, but it is billed in 2015 and on the 2015 1098T, not this year's 1098T. How do I do my tuition paid?

I did attend school, but the office is saying it is on the 2015 1098T. When I go through the steps for deductions, it is asking for the amount paid and I have no clue since it was billed the prior year. Also, I did have education expenses during that semester, so they are deductions for this tax return. Please help.
