Is there a way to install Turbotax without Windows11 saying you need to exit "S" mode because the turbotax software isn't Windows verified?
You need to switch out of S mode. See this windows FAQ. The second item is how to switch out.

So crazy that Microsoft and Intuit aren't on the same pg as far as verifying the turbotax application so the "S" issue doesn't occur... Crazy.
