Deductions & credits

OK I can help.

As long as the cost (or basis) of the land was more than the $15K you recieved there will be no gain or loss on the return. 

You will report this under Investments and you will show $15K as the cost (if the property cost at least that amount) and then the new basis of the land will be reduced by the payment and you will pay no tax.

To enter your Investments sold

Click on Federal Taxes

Click on Wages and Income

Click on I'll choose what I work on

Scroll down to Investments

On Stocks, Bonds, Other, click the start or update button

Please follow this answer I gave someone else on this same issue.
