I got a letter(CP 2000) from the IRS saying I owe 2,037 because of my education credits. After reviewing them I claimed the wrong Amt. what do I do?

I got a letter(CP 2000) from the IRS saying I owe 2,037 because of my education credits. My school sent a 1098-t that said my tuition was 303.50, and in book/expenses I claimed 1300. After looking back, I used the wrong information for books/expenses, and it really only came out to 572.72 for 2015. Do I need to amend my return? How do I get the amount adjusted?
