Are their multiple IRS forms 1099-K or one IRS form 1099-K?
Are you reporting multiple rental property activities or a single rental property activity on Schedule E Supplemental Income and Loss?
Keep the 1099-K in your tax records and report the rental income directly on each rental property. The key is to have the income in the right locations and a direct 1099-K is not required to file your tax return. In some cases it's easier, but not all.
