I need to report profit distributed (from rental) with LLC members in Sch K-1,box 19. Where to enter the distributions in the step by step method in business version?

It depends on what kind of business return you are filing, but generally, you need to enter partner/shareholder distributions in the partner or shareholder information section.

Under Partner or Shareholder Information on the Business Info tab, you can click Done Entering on the summary page.    The next question asks about distributions and you should answer Yes and add the distribution value as appropriate.
