Update. All of the descrepancies have been resolved. FYI- The amounts reported on the 1099K form are amounts either swiped, chip read, or manual input from the customers cards. This is a gross amount and not the amount actually deposited. Uber takes significant fees from the driver's which I knew. I think the taxpayer in this case led me down the wrong road by starting this conversation stating that Uber told her these were the amounts she received which was indeed incorrect. After I deducted the UBER fees, the amounts matched the bank deposits perfectly. So, note to self, don't let the client confuse you. I feel a bit embarrassed by this but will use the excuse that this all came about at a time when we were experiencing various technology issues and my brain was partially out to lunch.
