Student loan interest on your e-file tax - How To Make a List

When I try to e-file tax my federal Student loan interest, and I have no interest to include student loans. In 2006, it consolidated my loans so I have total 3 Student loan interest different lenders and work for three separate buildings. How do I include this information in my spreadsheet? I understand that with a total list of lenders is the Student loan interest information society, it is now, and where can I find the identification number for my Student loan interest lender?
