How do you turn off a stuck gas or water valve?

Stuck valves often feature safety locking mechanisms or resist turning due to infrequent use over time. Applying too much force can damage the line, preventing homeowners from safely stopping the flow for appliance repairs or emergencies.

    Turning off the water line to the water heater

First time homeowner and not sure what I should be doing.source ↗

However, I am reading that we are supposed to be turning off the gas line to the heater as well and my inspector had put these tags when we initially brought the home that seems to be stating the same. I’m assuming this is the gas valve but I’m having trouble moving it and wanted to check that it’s the correct thing I should be turning off.source ↗

I'm trying to turn off the water to my toilet but I can't seem to turn it no matter what.source ↗

It isnt stuck, it has a bit of turn either direction but there's some kind of locking mechanism I think.source ↗
