Do I have to select Sign Out for Turbo tax to accurately save my work and let me start where I left off when I log back in?

Once you make a change to your return TT automatically saves it. But to be doubly sure that you have the latest changes its a good idea to either manually save it or when you're done, click on exit or sign out and select save return. May be a little overkill but at least you're sure you the latest changes you've made to your return.
