For tax purposes, Full-time does NOT mean at least half time.
There are two different purpose, for taxes, in student status:
1. You must be full time, for parts of a least 5 calendar months to qualify as a "Qualifying Child" dependent.
2. You must be, at least, half time to qualify for the certain tax benefits, mainly the American Opportunity credit.
The 1098-T only has the half time or more question because the IRS (who mandates the form) is only interested in the school telling them if you qualify (based on status) for the credit.
At least twice, in the interview, TurboTax (TT) will ask you if you are Full time.
So, telling TT that you are fulltime for the dependent question, also tells TT that your are at least half time for the tax benefits issue. But, the IRS still wants it their way on their tax form.
