Deductions & credits

I sold a single family investment property purchased with an LLC.  I have done more reading, and think it should go on schedule C.  But if I did not receive a 1099-S, I still don't have to report it ?  If it goes on a schedule C can the loss carry forward ?
When asked on the 1040 if I had interest, I had interest in the business account that was used for this rehab … so it would be considered part of the loss in that property and therefore not reported.
