Screens normally go in the untrust zone. You can see in the counters to see what ones are hitting.

Those v1* zones cannot be used if your NS is in routing (versus bridging) mode. In bridging mode, the NS works like a switch.
With routing mode, you have a WAN and at least one LAN side. WAN is in the Untrust zone, and that is where the defense should start. So the prior answer is correct - you use Screening in Untrust most of the time.
