There are two education/tuition credits available. The more generous American Opportunity Credit (AOC or AOTC) is limited to only being claimed 4 times regardless of how manty terms you actually attended school.
When you follow the interview correctly, TurboTax will automatically award you the Lifetime Learning Credit (LLC). There is no limit on how many times the LLC can be claimed or on how long your education takes, But, be aware the LLC does not have a refundable feature like the AOC. It can only be used to reduce your actual tax liability.
