How do I itemize?
TurboTax automatically selects the federal deduction – standard or itemized – that works best in your favor.
However, you can override this selection by following the instructions below.
Note: You'll be prompted to upgrade to TurboTax Deluxe, as Free Edition and Basic don't support Schedule A.
To itemize, search for itemized deductions, choosing in your TurboTax program. Be sure to use this exact term, including the comma and space.
Then, in the search results, click the "Jump to" link. This will take you straight to a screen where you can change your deduction.
