I work in sales and receive a w2 I drive for that job and have mileage to claim, I also drive for rideshare and have mileage to clam, how do I separate the two.

The mileage you claim for your W-2 job is considered Job Related Expenses, reported on Form 2106.  You can deduct mileage from your office to your client's location.  You need to keep track of this mileage. Or, if you work out of your home office only, you can deduct mileage from your home to your client's location.
