The forms etc. on my chromebook app are only using about a third of the screen, how do i adjust this?

This link from the Google Chromebook website has more information on this issue: App uses only middle third of display. 

Also, the client can try using TurboTax Online instead of the app, if the app doesn't display properly. They can use the same username and login information. 

If you require further assistance please contact our phone support team or contact us directly on Facebook or Twitter. 

Thank you for using TurboTax.
