We sold personal property (land) and made a profit. Where do I enter expenses / improvements to offset capital gains?

[Critter-3]

When you are asked for the cost basis  that amount is the total of  the original purchase price + cost to buy(if any) + costs to sell (if any)  + improvements made while you owed it.   You enter only ONE figure in the program.
