I don't know what video you are watching, but in no case do I see a Range Mask as you have detailed it...however, you are using the term 'filter' (within the Develop Module) which isn't something stated in LR - in PS, it is indeed used.
I have the same PC OS and LR version as you.
Can you tell us what video you got this information from?
But I think I finally found where they put it in the new version...see attached photo.
