I received a 1099 nec even though i did not work for them in 2020 trying to fix with them is a nightmare should i add to 1040 even though i sent money back?

You can add it as other income and then back it out again with an explanation. "Incorrect 1099-NEC. Repaid"

• Wages & Income
• I'll choose what I work on
• Less Common Income select Start (or Update) for 
• Miscellaneous Income.
• Other reportable income and you can enter your own description(s) and amount(s).

thanks!!! mike
