How to enter Americorps Education Award?

I received an Americorps Award for $5815 for 2018, and used that all toward my graduate degree costs. 

How do I file this so I don't get charged a self-employment tax? Secondly, how do I prove that I had this directly sent to my university? Should I just say I spent $5815 on my education costs for this past year? 



Note: I see similar questions were posted before, but nothing for this year. I want to make sure everything is the most updated, and to ask specifically how to prove that I used this money directly for my tuition for grad school. 

Thank you
