Beginner question about phone footage.

I took some video before I knew I would be editing anything and I did it in portrait mode. When I import it into resolve it sets it horizontal and I can't figure out how to set it back vertical so things are right side up when viewing. I know this is probably something simple, but I can't seem to figure it out or find help on youtube etc. Anyone know How I can keep the original vertical footage for editing and rendering?

Thank you kindly and sorry if this is not in right section.
