1099-Misc that is not me

You are not required to report income that does not belong to you. If you know you did not sell anything on Facebook or the only items you sold were personal use property that was sold for less than you purchased it for, there is nothing to report.  

• Meta Marketplace is a place for people and businesses to discover, buy and sell items listed on Facebook within their local community.

If you remember selling any single item for a profit, it must be reported on your tax return. This would be similar to a yard sale of sorts.

• Do I have to report personal items I sold at a yard sale or similar activity?

If you received an erroneous 1099-Misc, you have several choices:

1. Ideally, you get a corrected 1099-misc from the payer
2. Don't report it on your return. Attach a copy of the 1099 and a statement explaining the circumstances. You can't e-file. From the old IRS instructions for form 1099-Misc: Form 1099-MISC incorrect? If this form is incorrect or has been issued in error, contact the payer. If you cannot get this form corrected, attach an explanation to your tax return and report your income correctly.
3. Report the income as misc line 8z, Schedule 1 income  (enter in TurboTax at the 1099-MISC screen and identify it as sporadic income ["did not involve intent to earn money"]). Then enter a line 8z deduction, for the same amount.  In TurboTax (TT), enter at:
   - Federal Taxes tab
    - Wages & Income
   Scroll down to:
   -Less Common Income
         -Misc Income, 1099-A, 1099-C
          - On the next screen, choose – Other reportable income -  Answer yes to Any other Taxable Income -On the next screen, Enter the number with a minus sign (-) in front.  Briefly explain at description. Call it something like "erroneous 1099 received"
4. Do nothing and hope you can explain it away when & if the IRS contacts you
