Deductions & credits

Where in the interview does the software ask about my percentage ownership for form 1120-S? I can't find/revisit the question, nor is there an opportunity to check off whether or not I paid my own health insurance premiums - is this asked somewhere else?  The guidance on this topic also only seems to refer to form K-1/1065; it doesn't mention 1120 even though it is phrased as if it applies to both forms.
