I recently went through this questline in Shadowlands. I tried everything that the previous comments suggested. None of it worked for me. After going through warmode on/off, turning the assault on and off from BFA, resetting the quest and watching the cutscene countless times, what worked for me finally was watching the cutscene completely through, logging out with the quest ready to be turned in and logging back in. Hopefully this helps and he shows up for you eventually!
It's 2022 and this quest is still bugged. After the cutscene, my body was placed on top the turn-in question mark on the minimap, but no one was standing there. I ran back to the house and Schnottz was still standing there as if I never saw the cutscene. After logging out and back in, Harrison showed up and I was able to turn it in.
Item facts are the current retail client’s (ItemSparse); the specialisations for a pick-one item are the ones the Blizzard quest API lists; faction and currency text is the client’s own. Lowest listed price = the US commodity auction house now.
Pins are the quest’s own POI points from the current retail client, projected onto the in-game zone map. The game marks one blob as the quest’s turn-in; the rest are objective areas. Points that fall outside a map’s window are dropped rather than guessed at.
Quests whose map markers the client places closest to this one on Uldum, nearest first. Distances are straight lines between the markers.

So, listen to this, <name>. I knew that these obelisks were linked to the Coffer of Promise, but there's more to it. There appears to be something very important about the coffer - something pertaining to a place the Makers called the Halls of Origination.
