Being permanently disabled does not affect your federal tax return, so the federal section of TurboTax will not ask about it. Some states might take your disability into consideration on the state tax return. If your state is one of the ones where it makes a difference, the state interview will ask about it.
Being permanently and totally disabled could affect whether someone else can claim you as a dependent, but many other factors are involved as well. In the Personal Info section of TurboTax it asks whether anyone can claim you as a dependent. If that is a possible consideration, you should check the definition of total and permanent disability, and the complete rules for whether someone can be claimed as a dependent.
