Mileage Expenses Question for both W2 and 1099-MISC

Hey everyone,

 

I have a W2 which accounts for about 90% of my income but just started doing some contracting work and for the first time have a 1099-MISC.  Yearly, I drive roughly 11,000 miles - I only own 1 vehicle and use it for personal use, driving to my main W2, and also to my side 1099. My question is this - On my 1099, I only claimed roughly 300 miles out of the year as my deduction (just getting started in the new venture). Can I claim additional miles to my W2 that I drove to that main source of income? I would break out the personal miles from the equation.

 

Thank you!
