Thank you for this info.  A couple follow up questions when preparing the 1040:

1.  On Schedule K-1 for  year 2019, there is a new section, Box N - Partner's Share of  Net Unrecognized Section 704(c) Gain or (Loss).  The beginning balance is $100,000.  The ending balance is $400,000.  Do we need to enter this information in Lacerte when preparing Form 1040?  
Is this just for informational purposes?  
Does this information need to be reported anywhere on the 1040?

2.  Is this taxable on Form 1040?
