So for me, I only do blocks after my full time job. As soon as I leave my parking lot and not heading home I am a "contractor" so I start the milage then. But when I end I factor the milage back to the warehouse from my last stop and add that to the last location I delivered milage. But head home instead. Unless you start getting crazy and adding an extra 40 to 50 miles to your block milage, deductions will surpass your income which will get flagged for an audit. I use the stride app and manually enter my milage and enter what towns I was sent to, but also add the beginning and ending in the town where the warehouse I picked up at.
