Proof of Enrollment and Reporting Outside Scholarships

For an outside scholarship I received, I need proof of enrollment. They said that I couldn’t just send an acceptance letter, I need an actual class schedule. My orientation isn’t until Mid-July and I wanted to get some type of proof before I get my eFAN so I could report it. My question is: Can I get proof of enrollment of any type before I receive my eFAN/how would I report the scholarships after receiving my eFAN?
