if the activities qualify for 199A, the partnership MUST provide this info on the k-1 because the IRS can check what you enter vs what's on the k-1. so you need a corrected K-1 if there is 199A info which sems likely. did you look on the back of the k-1?.
not sure what you mean by 199A dividends. Only certain REIT dividends qualify for 199A. they would be included on 9a and possibly 9b and the amount would be 1 of the 20Z items - separately reported.
business 199A info must be reported separately form real estate 199A info because Turbotax requires each activity - line 1 and line 2 along with the relayed 199A info to ne entered on separate k-1s.
gains are never 199A income and distributions reduce your tax basis and are neither income nor expense so also are not 199A items
