You should receive a Form 1099-S at the time of closing that reports the sale to the IRS.  The sale is reported as an investment sale on your tax return.

If using the TurboTax online editions you will need the Premier edition to report the sale.  If using the TurboTax desktop CD/Download editions, any edition can be used.

Most likely, you report it as a  business profit on Schedule C.  Alternatively, you report it as a capital gain on form 8949 and Schedule D.
