Get your taxes done using TurboTax

Are you on Windows?   How are you trying to start a new return?  Are you going up to File-New Tax Return?  Then what do you get?  A box to Continue an existing return?  Do you see the 2 blue buttons to Start A New Return  and Continue from Turbo Tax Online?

 

Have you updated the program?  Go up to Online-Check for Updates.  If you are on Windows there may be some Windows updates to do also.
