For 2019?
You need to report the sale of the first house if it was disposed of in 2019.
You can add the beneficiaries, but you do not need to issue K-1s (or even generate them) if there were no distributions (deemed distributions or otherwise).
Since there was no distribution in 2019, the trust would be responsible to pay any tax due on capital gain from the sale of the house in 2019 (if there in fact was any gain).
