"and not patronizing comments"

Well, I think you would see the peer users contributing their volunteer efforts are not patronizing. Maybe a little snarky and frustrated now and then.

This is not Intuit's customer support (but is mistaken for one), and it really is meant to be a "how to use" and not Tax Rules, community. A lot of postings this time of year are either TurboTax users who are lost on the internet, or purported preparers that haven't bothered to know the most basic details of what they are doing (and often are foreign and might even be AI nowadays).

Of course, we all learn from each other. Some people just don't pay attention.

I do speak for myself when I point out there is an expectation, when very basic questions are asked, or the question requires up to date information due to a bazillion tax code changes and retroactive ... that the person asking could have looked first, using a google search even. But everyone had a "first time" moment, that they didn't know something even existed, so we provide info and bookmarks and resource references.

Also, when someone keeps asking the most basic questions, and especially when their further input shows they want their own intended result, not the "right" result, that you see the snark come out.
