Fluid simulation How can I move fluid simulation animation to different frames

I would like to move the fluid animation to the frame I need, for example, by 20
And how to get fluid animation keys

Fluid Settings are animatable like any other setting.

Animation keys and animation curves are visible in animation editors as long as active object is the animated one.

To offset a fluid animation, you just need to bake it. Then, under cache panel, you just have to set Offset value to 20.
