Maryland Military Retirement Pay Subtraction

Why TurboTax does not show the $15,000 military retirement pay subtraction I normally get when I file my Maryland state tax return.  In fact, in the forms view, the subtractions form (i.e. 502SU) doesn't even show up.  Is 502SU just not developed yet by TurboTax?  If so, when is the update projected to become available?
