Uber net payout is different then 1099 NEC nonemployee compensation

The net payout number would be the amount they paid you minus any fees they withheld from your earnings. 

For instance, let's say you earned $10 and they withheld $1 for their fee. Your net payout would be $9.

Your 1099-NEC would show $10 because this is your gross earnings from them.

Continuing with the example, on your tax return, you have income of $10. Then you also include your expenses on your return. $1 would be the expense for Uber Fees, and maybe you had another expense of $2.  Your net income (or profit) would then be $7. 

This is an oversimplified example but I think it will make sense. When doing your taxes, you do not use your Uber net payout numbers.
