Deductions & credits

Thanks @JamesG1  The 1099-k from paypal also includes money that is not income from profit, e.g. money for free product trials (e.g. Rebatekey) for items you pay for but you get the money back via Paypal, or other online survey money (otherwise below 1099-MISC thresholds). How can one 'deduct' these from the total 1099-K number as they are not income, and in fact dont have anything to do with the' business'.
