Independent contractor needs help understanding miles (please read)

hi.

I am an independent contractor who goes to location A from home, does my job, then goes home. From my understanding those miles to and from work aren't deductible. I've never written these miles off. Please correct me if I'm wrong.

I, recently, got another contract. So I now go from home to location A, then to location B, then home. Are the miles from location A to B deductible?

Thanks for your help in understanding.
