K1 syndicates, 1065 and sale of the syndicate

[Sonu Sundar]

I have few apartment syndicates 
First 2 syndicates being sold. we do taxes in the  turbo tax and there are several questions I have, the biggest being how do I figure out the cost basis and the sale price from the K1 and Form 1065? I have tried to locate information from my usual sources (You tube and the web) with no satisfactory results)
Please provide me some information, links or easier, or contacts who can provide consults for small fee.  Rest of the tax issues we are able to do with turbo tax.

Thank you
