1099-S Proceeds From Real Estate Transactions, trans

I sold a home in 2017 and didn't receive a 1099-S form from the IRS to report gross proceeds. To settle a discrepancy where do I report this information on the form? And what form should I use to report the proceeds? How can I go back into my Turbo Tax account and report this information pertaining to that year? Or can I submit that information on this years tax filing?
