This has been occurring with customers
that are using the Chrome browser. We are currently unsure of what Chrome
setting is causing it, but TurboTax Online saves your return after each screen
in case one were to get disconnected accidentally. So you can go a neutral screen where you are not
inputting any data, and then close the browser.
If the problem continues with your Chrome browser, try clearing
your cookies and cache or you can try another browser such as IE or Firefox
(Firefox works best with TurboTax).
