I received my 2009 1098-T which had my amounts billed + grants listed. Yesterday I received another with a completely different amount (lower amount) on which box 7 was checked. I didn't pay for this semester until the first week of this year. Am I still supposed to add this to the other or just ignore it until next year?

Is later 1098-T has "Corrected" checked, ignore the first 1098-T.
