I tried it to see what it shows up as on activity, all I see is "home" but nothing about incognito. Is that how it works for others? Checking on a teenage daughter who has tons of data used but no web or app activity

You are referencing a web browser right? I'm assuming so. If that's the case, then yes, incognito tabs will not appear in a browser's history. You can check which apps are using data as well as how much in the device settings. Open settings and head to:

Data/Data usage

The apps should be listed directly below the usage chart. I'm willing to bet it's a video or streaming app like YouTube. Apps like this eat a crap load of data, especially HD streams or videos.
