Student loan interest

 

I have two student loans with the same lender US Department of Education that's through Great Lakes. (they're both in my name) I've got two questions. Do I need to list the student interest on these two loan separately or can I combine the interest from the two loans since they're both in my name and the same lender? Also when I list the name of the lender should I list the US Department of Education and Great Lakes or is US Department of Education enough information? Thanks
