High ISO makes for a noisy picture. You'll have camera movement at 1/20sec, plus you have no flash. Don't know how dark the area was, but you could try using an ISO around 800 to cut noise. Shoot at least 1/60 sec. Try shooting in aperture mode. BTW, I have the 80D and use an external flash. Never in auto(green zone).
Aperture mode would have the shutter speed way slow. To force it faster, it would have to be in Shutter preferred or manual modes.
