I received benefits from the Department of Rehabilitation’s Vocational Rehab program where they pay my school expense. How do I reduce this since it’s non-taxable income?

The Mississippi Department of Rehabilitation Services program paid for my tuition, rent, food, and toiletries. I was told this is nontaxable income by them, so would I just need to subtract their tuition payments to the school since they paid directly to me as an off campus student? How would I go about this on my tax return?
