I recently started working as an UberEats delivery driver and I need to make quarterly tax payments. How do I figure the Adjusted growth income (AGI) for line 1, on the Estimated Tax Worksheet? I'm confused, because I don't know where I am able to enter my deductions, like mileage. Isn't mileage a part of the adjusted growth income? If not, how do I minus that deduction from what I owe for my quarterly payments?
