I don't think you can turn in Writs into Hew's Bane, so it will say the same for you. All of my characters are still getting and turning in writs from and to their normal locations.

Gotcha thanks. Is the zone small? It looked small on the map...

Yes, the zone is quite small. Presumably that's part of the reason why this DLC is cheaper than the others so far. The quests do send you to various places around Tamriel though (including sending you to various alliance zones from the base game, and some solo instances that aren't in Hew's Bane and don't show up anywhere on the map), so when you're doing the DLC you won't be spending all of your time in Hew's Bane.
