You probably should pick up the phone and talk to the lawyers about this so that you understand exactly what your responsibilities are. Is your name and Social Security number on the 1099-S as the seller?
If your father's estate or trust sold this house, i.e., the title of the house was not transferred to you before the sale, then the estate or trust should report the sale and pass through to you any information you need for your income tax return on Schedule K-1 - "Beneficiary’s Share of Income, Deductions, Credits, etc." However if the house was retitled in your name and you sold the house - handled by "the lawyers" presumably - then you'd need to report the sale on your income tax return along with any associated gain or loss.
Typically the basis for inherited property is "stepped up" to the property's "fair market value" at the date of death so a sale of that property shortly after the act of inheriting wouldn't be expected to report much of a gain, most likely a possible loss because of selling expenses.
