Without knowing the finer details of the explicit typeform for NewsItem, i could imagine the reason for it to be there is to have better control of the labeling and layout when editing. Like Tabs and such, which is hard to control when letting C1 autogenerate the form.
But i agree that the documentation about enabling publishing should be more specific about how to make the textboxes appear if the form isn't autogenerated by C1.
