I'm reviewing my tax return and trying to use the QuickZoom feature but can't figure out how to activate it. How do I use the QuickZoom feature?

QuickZoom is only available in forms mode in the CD/Download TurboTax software. It's not available in TurboTax Online, which does not have forms mode. This is one of the many advantages of the CD/Download software over TurboTax Online.
