I’m praying my washing machine in the garage doesn’t bust open, the knobs were frozen stiff when I left and couldn’t shut one off.

Don’t know the vintage of your house or the type of water pipes installed. Some of the newer homes with PEX plastic tubing (usually red or blue) can apparently tolerate some freezing. Traditional copper tubing, not so much.
As a last resort, you can shut off your water main where it enters the house. Usually there is a hose bib or faucet located above the shutoff which can then be connected to a garden hose to drain the water from the lines.
A burst water pipe under pressure can really be a nightmare.
Built in the mid 80s, it’s all copper. I had a bathtub knob break and was spraying, disaster barely avoided. This time I can barely check on the place. Probably stuck away for awhile now.
