Skipping 1098-T as a fully supported graduate student

Hi, I am a full-time graduate student that is fully supported by my school through teaching assistant-ship. That is, my school pays my intution, admin fees, and health insurance. I just received my 1098-T, and I realized my tax return dropped significantly after I entered my 1098-T. After doing some research, I realized that is because my Box 1 is about $5000 less than my Box 5 because of fees and health insurance. But none of the money was used for room and board. They are solely health insurance and admin fees.

 

Isn't 1098-T supposed to help with my reduction, not harming it? So I wonder if I can exclude my 1098-T form.
