Saw the same thing just now doing my own taxes. TurboTax's amount was different than what was on my state tax return. But I took a closer look, and the difference between the amounts was the Earned Income Credit. So subtracting that from the total refund amount on my state tax return gave me the amount that TurboTax had filled in. I'm not sure why they don't give any clarification on this, since it seems pretty confusing.
