I have income from Uber, DoorDash, Postmates, and Amazon Flex. From what I can determine Uber uses the rideshare business code of 485300. The other three seem to be covered by 492000 - Couriers and Messengers. I know Uber will not issue 1099-k as I am under $20,000. I don't know about the other three. Would I do 2 schedule Cs, one for Uber, one for the other three since they all have delivery in common? If so do I divide common deductions up into percentages based on share of income, like cell phone expenses I use for all of them?
