I took a couple of classes in the beginning of the year (after my undergraduate degree) and then I went to nursing school. I got 2 1098-T (one for the extra classes and one for nursing school). I took the 4 years of the undergraduate AOC, do I qualify for the lifetime credit now?
Yes, you should be eligible for the Lifetime Learning Credit.
For the Lifetime Learning Credit there is no limit on the number of years you can use this credit for undergraduate, graduate and professional degree courses. This includes ones to improve job skills.
In TurboTax you need to first enter your tuition statement - form 1098-T. The software will ask you a few questions that will generate and apply the lifetime learning credit to your return.
For helpful information on Educational Credits here is IRS information on Lifetime Learning Credit.
