Vents covered up

Hope someone here can help me get started on a problem: my house gets COLD in the winter--it is a ranch style home built in the 60's. In trying to figure out why, I noticed that I have NO return vents in the living room, kitchen, or entry way. I figure that it is so cold because the cold air isn't sucked out when the heater comes on. I believe (hope) that the previous owner simply covered up the vents when he remodeled--put drywall up without cutting out the HVAC return vents (the air comes out of the floor). Is there a way from me to find / verify if the HVAC return vents are simply covered up? Thanks.

You can go to the furnace and trace the ductwork. The supply side will be hot when the unit is running; the return, if present, would likely be cool to the touch.

You may find that you have an 'open' return, i.e., just open space between the furnace and a source of air (no ductwork).

The furnace must have return air in order to supply heated air. Do you have noticeable airflow?

Duct work

I can see the return vents for the basement, bedrooms, etc...the issue the basement is partially finished and there is no way for me to trace the vents to the living room (ranch, so the living room, kitchen, etc...) are on a slab adjacent to where the mechanical room is.
The vents do push hot air, I can feel it coming through in the rooms in question. However, the cold air has no way of getting removed--I think the drywalls just went up and covered what used to be there.
