You don't need to report anything at all to the IRS on any form for this sale since there was zero gain. Also, the 1099-S is only sent to you. It is NOT sent to the IRS or anyone else for that matter. The 1099-S is basically "for your information" and if it shows a gain, can be useful for your tax return. But the IRS does not get a copy of the 1099-S unless YOU personally send them one.
If your state taxes your income, I do not know if you will need to report this on your state return. So if this is the case, state what state you pay state taxes in, and someone familiar with your state tax requirements can provide you necessary information for your state tax return.
