If you have downloaded/installed the desktop software, entered your license code and updated the software, then you launch the program from your own hard drive. When the program opens, then click on "Begin"or "Start new return".
Be careful......
We see people get confused and they keep logging in to online software which will require them to pay at the end. You need to use the desktop software. One way to tell if you are using the right software---your tool bar. Online software has the toolbar in a black vertical column on the left side of the screen. Desktop software has the tools up on the top of your TT screen.
