How do I change from the cash method to the accrual method?

I have always used the accrual method.  

When I started my tax preparation in TurboTax, the system prompted me to choose my accounting method.  I incorrectly selected "cash" when I was prompted in TurboTax. 

Where within TurboTax can I navigate to so that the system knows that my method is actually "accrual."

Thank you
