You changed your mind, and want to e-file your tax return(s)
instead of printing and mailing. As long as 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.
On the other hand, if you already mailed your return, don't e-file. This can cause problems with the government, including refund delays.
If you wish to change how you'll file your taxes in TurboTax,
follow the steps below for either the TurboTax Online or TurboTax
CD/Download version.
There are options before filing to save a PDF file you can
use later to view and print the tax return (Adobe Reader or equivalent
is required for viewing and printing).
