I went to higher education for more than 4 years, but can't figure out how to let the program know that I don't qualify for the American Opportunity Credit.

I've attended Indiana university Southeast for more than 4 years, and one of the stipulations of the American Opportunity Credit is that it is for students in the first 4 years. This should preclude me yes? How do I let the tax program know this and take the deduction out of the file?
