I found the issue occurs when you dont go thru the step by step questionaire and skip a step manually.
Go to search topics, type "education" and go to the first top link that comes up
It goes to "education expenses summary" - click edit the school
It goes to "Here's your education summary". At the bottom, there is a "Education Information". Edit that and go thru the questionaire. If you do that, it removes the $10k deduction. Evidently you need to do that step for turbotax to run the calculation correctly. Otherwise it calculates wrong. That is a critical step!
Otherwise you need to fix it manually and override the $10k like people suggest.
