If our Daughters college did not give us a 1098-T form, for her Spring 2018 semester, how can we deduct the $2,600 tuition?

Our daughter is being claimed as a dependent on our joint return. She contacted her college last month asking for the 1098-T form, since the form had not been mailed to us. She was told that she would not be getting one, since she did not attend school for the 2018 year.   Which is wrong, since she did attend classes for the Spring 2018 semester, and the check for tuition was written Feb 2018. 

Not sure how to proceed without the 1098-T form.
