Quick question I'm right in the middle of this Thieves Guild quest, at the Goldenglow Estate and there's bandits swarming everywhere. So I read my quest notes and it didn't say. But, since a lot of TG quests involve NOT killing, I'm wondering what to do, so I don't fail the quest.

Thanks for any help.

You can and it never seemed to have any repercussions when I had. You have to kill a few in the house anyways so it likely won't matter.

Its easier just to shoot a bow enchanted with fire at the beehives or shoot a firebolt/ball. Once inside then you'll have to kill a few unless your sneak is very high and you have invisibility.

You won't fail if you kill anyone on this quest. Even if you kill the owner of the estate it won't matter.

tiny bump, just to see if there's any other input

This is not oblivion or other elder scrolls games. The thieves guild do not care which mercenaries or bandits you have to kill to get the job down so yeah it does not really matter. As Griffix said.
