They provide a 1099NEC for this income. For the past 3 years I have provided documentation to the IRS and they say I do not owe self employment taxes. Since KW won't correct the 1099 I don't know how to enter the income into TurboTax
Form 1099-NEC is generally intended to be used for nonemployee compensation that is earned by a contractor or other self-employed individual, but you can enter it in TurboTax and identify the reason for the payment if it was other than self-employment income:
For more information on Forms 1099-NEC, see this TurboTax article.
I would suggest you inform the IRS that this is the 4th year in a row the income has been incorrectly reported as earned income on the 1099-NEC. Maybe they'll finally take action against the issuer. (Probably wouldn't be cheap for the issuer either.)
