What is Quickzoom and how is it used?

[PatriciaV]

Quickzoom is a feature in Forms Mode that is available only using TurboTax CD/Downloads. Clicking on a Quickzoom button on a form or worksheet will open a related worksheet or schedule that provides more detail or supporting calculations for the current line item. See example in the screenshot below (click to enlarge)

If you are using TurboTax Online you will not have this option.

how can I find the company Principal Company code on a 1099-nec

From 1099-NEC does not have a field for any codes.

If you are referring to NAICS & SIC business code numbers, then you can look them up here.
