We have a new 2020 picked up prior to this virus mess and I’ve picked it up on our two post lift. There are both slotted and round holes when looking underneath behind front wheels and in front of back wheels. Caution is to use slotted holes to lift from and not round hole area. The tech used a rear round hole and upon lifting the lifts arms just tore thru the body.

GM has a document showing the lift points and using the J-43625 lift adapters in the slotted holes. Probably a video in the training catalog also.
