Tax help for military filers

I appreciate the assist but that's not true - at least it wasn't for me. The screen you showed never came up for me. The one that did only came up once I changed the selection.  Prior to that, I went all the way through the state return and it never came up and it was showing me owing taxes for all my income.  That's why I posted my question.

 

Why the statement about reviewing the entire return before filing?
