Deductions & credits

It sounds like you are using TurboTax Desktop. 

Please return to 

Deductions & Credits 

Select "I'll choose what I work on"

Scroll down and select "Done with Deduction"

Next screen should be an analysis on the "Let's Check Your Deductions and Credits" screen

Click CONTINUE

The program might ask additional questions about additional possible deductions and Sales Tax

You should eventually get to the "Here are your (tax year) Deductions & Credits"

Click CONTINUE

The next screen should show what the program chose for you and allows you to change the deduction, and allows you to select the method you prefer.
