Problem:

I have created Post Field, for specific Post Forms . But my custom field are in All Post Types.
I can't find a way to change it

Solution:

You can edit the field groups mentioned in your screenshot, in section "Settings for the fields group", option "Appear on", change the post types as what you want.
