K-1 - Complete disposition vs. Disposition was not via a sale

I am looking for clarity on how to enter information about a Final K-1.  I am a passive member of an LLC that sold the buildings to a third party in 2020.  Since the buildings were sold by the LLC, the LLC has been dissolved.  I received my final distribution (Box 19).  Amounts for 1250 gain (Box 9c) and 1231 gain (Box 10) are listed in the K-1.  I understand how the enter the Box 9c, 10, and 19 information into Turbotax.  However, I am confused on how to categorize the "sale".  I have seen different posts in the discussion board including one with a response from @Rick19744 indicating to mark "Complete disposition" and use my distribution as the sales price,

while another with a response by @DavidS127 indicates "Disposition was not via a sale" and to not enter a sales price,

Conceptually, entering no sales price seems accurate since I did not sell anything, but also seems like a red flag to the IRS.  I have been tracking my basis over the years, and while it is close to the final distribution, it is not the same.  So if I enter this into Turbotax, I end up with a small amount of long-term capital gain on that difference.  I want to make sure this is accurate and that I am not being partially double-taxed.
