It depends. Did you receive two Forms 1099-S? If so, you have two separate sales to report: 1) your homestead and 2) land held for investment. If, however, you did not receive Form 1099-S, the result of those two sales could fall under the IRS home sale exclusion.
Please see Is the money I made from a home sale taxable? for more information and instructions on how to enter this information in TurboTax.
If you need to report the second sale separately, go to Income >> Investment Income >> Stocks, etc., and choose "Land" as the type of investment. You'll need to allocate your basis (cost) between the two sales, most likely on the basis of acreage since no structures were sold.
