Get your taxes done using TurboTax

There are two different screen share programs.  The first is called Smartlook and the agent sends you a pop up box and you agree to share your screen.  You can also see the agent.  They cannot see any personal information.  Sometimes the agent want to see more than the allowed information and will ask you to run a program called Glance.  That allows everything on your screen to be displayed,

If you are seeing a blue box on your screen, then that agent may still be connected.  Restart your computer is you think that is happening.  The agent has no way to send you a screenshot of what they are seeing.
