Yes, to back out of menus just use the "Back" button at the bottom of the page. Additionally you can click the an area in the left hand menu like "Wages and Income" to jump to the main screen of that section. Once on the main screen for "Wages and Income" you can scroll down to "Other Common Income" where you will find the "State refund" topic.
Keep in mind if you used the standard deduction last year then none of the state refund will be taxable. If you itemized last year then TurboTax will help answer a few questions to see if any of the refund is taxable.
