Yes from home to first destination and last destination back home are commuting expenses, not deductible.
But you can deduct mileage from first to second job as an employee business expense.
To deduct employee business expenses, you must have enough itemized deductions (ie. Medical, mortgage interest, property taxes, charitable giving, ect) to exceed your Standard Deduction. If you itemize, your deduction is limited to the extent that it exceeds 2% of your Adjusted Gross Income.
