I see, the problem is with the online version when Smart Check flags the error. The only thing that you might be able to do is delete the Form 1099-NEC and reenter it in the business section. When entered there, TurboTax will likely create the link to the business under which the Form 1099-NEC is being reported, eliminating the error, but I can't be certain since there are presently so many flaws in the implementation of this new form in TurboTax.
