I know my Uber mileage for 2016. I don't know what to put in "Total Commuting Miles" under "How do you want to enter your mileage for your [car make]." Please help.

First, I apologize for this extensive question....

I drove for Uber. I know my start (20,610 miles) and end (34,324 miles) odometer readings for 2016. Often, after finishing my substitute teaching job at various schools, I did a drive or two before heading home. I never counted the mileage from that school to my first rider pick up. I did keep track of miles between drop-offs and consecutive pick-ups (45 miles). I also kept track of the mileage from the last rides to my home (219 miles). It sounds like I can deduct these both. Is that correct?

Uber's summary sheet shows that I drove 244 miles while on trips. In TurboTax Home and Business, I don't know what to put in "Total Commuting Miles" under "How do you want to enter your mileage for your [car make]." I commuted to different schools and to another job driving buses but didn't keep track of that mileage.

I put 508 (219+45+244) in the box for "Miles driven for this business." Again, I didn't count miles from my home to the first pick up or from a school (other job) to a pick-up.

Also, since Uber drives are all temporary, and my "business" is always away from my home, is the job considered to be temporary or indefinite?

Please help. Thank you.
