You don't report your business income on your personal return. You would only report your share of business income/expenses by reporting Schedule K-1 on your personal return.
In other words, if you have S-corporation or Partnership, you file that business using business software(which I think you did since you have the K-1). Then, you report only K-1 form on your personal return.
The business section you are referring to is for self-employed individuals filing Schedule C, not S-corp or Partnership (which are the entities with Schedule K-1). So you would not enter your business there. All you have to do is enter your Schedule K-1.
