I don't use Turbo Tax, so I can't provide any information or advice as to how Turbo Tax gathers or uses information, but as noted in the article you linked to in your other question, "When determining the tax treatment of your 529 plan withdrawals, the Form 1098-T is close to worthless. In fact, it can be misleading. Ignore it." In other words, don't rely on the 1098-T to provide accurate information. You must determine yourself how much was paid for qualified expenses, when, and from what source.
The value of tax-free scholarships will be used to determine the adjusted qualified education expenses so that you can calculate any non-qualified part of a 529 distribution. The numbers from a 1098-T and the value of tax-free scholarships are not reported directly on a tax form.
