My tax return was accepted by the IRS. I got a 1098 T in the mail today. My expenses are less than my scholarships and grants. My refund is too big. What should I do?

I filled my tax return before I got my 1098 T in the mail. I edited the information on turbo tax and ended up with a smaller refund than the refund I filled for. So if the IRS approves my return, my refund will be too big. Do I need to amend? Will the IRS tell me if I need to amend?
