Can I use the 1098-E form I received for my student Loans which was paid through Fed. Consolidation in 2016, despite that I made No payment to the loan in 2016 ?

I consolidated all my Navient Fed. Student Loans in 2016 to FedLoans. And now have received a 1098E from Navient. This is while I payed No payment on my loans in 2016 since I was in a IDR repayment program which had a 0 dollar monthly payment amount. Fedloans through consolidation paid my Navient student loans in full, in other words my loans with Navients were paid off and closed ( All principal , capitalized interest , etc ) were paid off. So since I made no payment myself, will I still be able to use the interest reported in 1098-E ??

Lastly , If my brother claims me as dependent,  can he claims the interest on my 1098-E ? ( Given I was the sole person responsible for the Loan & Not him ) .
Thanks
