Where does the national guard tuition assistance go?

I received the GI bill and the national guard tuition assistance for school. It is not listed on my 1098-T. Does the tuition assistance go under the veteran's education benefits, the employer-provided assistance, or other scholarships and grants?
Also, I only went to school in the fall, so if the assistance is $7,000 per year, should I put $3,500 since it was only one semester?
