@Maureen-And--Peter0 1099s are designed to report the GROSS amount of monies that are applied to a property. So it is going to include the service fees paid to AirBnB on behalf of the property, fees paid and refunded to guests who cancel, etc.
Any amount of money that is processed for a property is included in the 1099 GROSS.
It is a total PITA to reconcile, which is why I keep a spreadsheet of every guest rental, cancellation or refund, all of the taxes collected from the guest, the fees that AirBnB charges the guest and the host, etc. Then I have a good chance of matching the amount shown on the 1099, and my accountant can readily assign expenses to reach the amount that I DO report as income.
