You may not need to
file a state extension -- some states don't require it. Further, of the states that do require
extensions, e-filing might be allowed, but only through their own portals.
Please see the
TurboTax FAQ "Do I need
to file a state extension? If so, how do I do this?" below for
guidance specific to your state.
