Sold My Residence to one buyer and the adjacent land to a different buyer in 2021. Treating it as one sale for capital gains exclusion.

The IRS treats the sale of the residence to one buyer and the sale of the adjacent land to a different buyer as one sale for the purposes of the $500,000 capital gains exemption.  I read where you enter each of the 1099-S separately in Turbo Tax.   How do I enter each sale separately and treat it as one sale?  If I enter each sale as Sale of Residence, it allows for the $500,000 capital gains exclusion each time, so that can't be right.  

 

How do I combine the sales as one when the sale dates were different, and there are two different 1099-S?  This answer is nowhere to be found.  Even the CPA I asked doesn't know the answer.
