Get your taxes done using TurboTax

If you don't break out each pass-through entity into a new Turbotax K-1 entry, and just add up all the pass-through entity figures to reach a total for each category, how does that effect the Ttax calculation of the section199A deduction?  What is the rationale of splitting it up?  What is the flow of the calculation?  Why is it necessary to create a new Ttax entity for each pass-through ein, and how will it throw off the result?  Curious. Thanks.
