Go through the education section again. Go through the entire education interview until you reach a screen titled "Your Education Expenses Summary". Click edit next to the student's name. That should take you to a screen “Here’s your Education Summary”. Click edit next to “Education Information”. You'll reach a screen asking how many times you claimed it before, Change it to something other than 4.
If you have used TT, in the past, TT will have picked up that number from previous year's returns, so be sure you're right.
You can get the AOC a TOTAL of four times for the student-----if you have used it four times it does not matter that this is the "4th year" of college.
