Re-Copied here:
- Click on the Forms icon in the upper right to switch to forms mode and open the form that contains the line item you want to override.
- Right-click the line item and select Override.
- On the Mac, choose Override from the Edit menu in TurboTax.
- Enter the value; it will turn red.
- Switch back to the interview by clicking Step-by-Step in the upper right corner.
To reverse the override, follow the same directions except choose Cancel Override in Step 2 (on the Mac, uncheck Override in the Edit menu).
When you run the final review, TurboTax will let you know if there are any overridden values in your return. If there are, you'll get an error message if you try to e-file your return.
