Thank you Turbo TaxMarilynG for pointing me to this information. In my case, there are no scholarships/grants. I am still confused as to why turbo tax is not including the amount of tuition not used by the American Opportunity Credit against the 529 plan withdrawal. I added the expense for books, a few hundred dollars, and that did not change the calculation. Could this be a problem with how the program is calculating these dollars or how I am inputting the information?
