Help with finding Smooth Stroke

I am now on the texture paint part of Blender Guru’s doughnut tutorial, but I don’t know where the smooth stroke feature is. I need to disable it as part of the tutorial, but when I press the menu, I can’t find it. I have Blender 2.90.1.

I’m not sure what you mean by smooth stroke see here : Blender Doc: Texture Paint (no smooth stroke).

I believe it is now Stabilize Stroke…where the cursor lags behind and smoothes the paint stroke…
