Thank you.
This is my understanding so far:
1. On a day where I drive to and from my home office for massage therapy to the W-2 job (which is an unrelated field), commuting cannot be deducted.
2. I had been writing down my miles driven from the home office to a chiropractor's office where I've worked longer than a year and get 1099-MISC annually as a deduction. However, since I see far more clients outside my home office, such as at the chiropractor's office, it now looks to me like this isn't deductible, as although my home office qualifies in the sense of exclusive use for business, it's not the place where I see clients most regularly.
3. Driving to a temporary work location from the home office, along with driving from between the first 1099-MISC location to a second one, along with driving afterwards to the W-2 location, is deductible.
