Dmdmd2020, this is as close as I have ever seen to proving the moving of monies will soon be moving into one's Escrow-ShareMarker account. You have tied together the Trusts, dates, timelines and the filing of DB information in early Dec/2017.
The statement from DB's filing saying the monies would not move before 2018 to me is indicative of them wanting to push to the monies into Jan/2018 due to tax law change.
You have done a wonderful job of tying all of this together and thank you for sharing your hard, time-consuming and challenging work for all to enjoy!
