If the real estate was transferred out of the S corp into a Family trust two years ago, there is nothing to do regarding the real estate on the final S Corp return, because all of that should have been handled on the filing two years ago. But, it is unusual (and not recommended) to hold real estate in an S Corp. Perhaps this person who owned real estate, also owned an S Corp. But the real estate and the S Corp have nothing to do with each other, setting aside common ownership.

As usual, more details will be helpful.
