I started my tax return, but now want to change from itemizing to standard deduction. How do I do that?

1. Click on Federal Taxes [Personal in TurboTax Self-Employed] > Deductions & Credits.
2. On the Deductions screen, scroll all the way to the bottom, and click Wrap up tax breaks.  [See Screenshot #1, below.]
   
3. Continue through the screens until you reach, We've Chosen [Itemized/Standard] Deductions for You.
4. To change the selection, click on the box, Change my deduction.  [Screenshot #2]
   
5. Confirm your decision by marking the radio button for Itemized deductions or Standard deduction and then click Continue.
