If
you haven't already mailed your 2016 paper return, you can switch to the
e-filing method (through October 17, 2017). Some states now require e-filing their returns, and
federal and state returns must be e-filed
together.
If
you wish to change how you'll file your taxes in TurboTax, follow the steps
