Tax law changes

OK, so in using the example numbers I gave, you're saying that my cost basis is $1500?

Which is what I put into the TurboTax form for "Cost and other basis"?

 

The only other thing is that I have no idea what the $200 tax basis is for. This limited partnership is now dissolved, so I will not be receiving any more checks or anything related to this land sale. Is this a problem for later? Do I need to find out what it is from the partnership?

 

Thank you!
