Because some states' returns are simple enough that it's not worth the TurboTax fee to do it through the software. Also, some states have their own e-file portal that only takes 15 minutes to walk through and then submit (free), so it's still not going to get lost in the mail or eaten by the dog.
Intuit is not omniscient. We, their customers, need to know which forms and other important procedures have been updated so that *we* can determine whether they affect our tax returns in ways that TurboTax may not be aware of. The decision to turn it into a black box and urge us to just trust them is not acceptable.
