Transportation and Travel costs for a sole proprietor

Where would I enter these types of expenses as an independent contractor, who works from home and does not have a single/consistent place of work? (When I travel for work, it is almost always a different location).

 

-Ubers/lyfts to and from a gig/meeting

-Public transit costs to and from a gig/meeting

-Gas/vehicle expenses to and from a gig/meeting

 

If you don't have a single/consistent place of work, are these considered business travel costs rather than transportation costs (does transportation mean commuting?)
