It still won't allow me to e-file Form 568, and other posts have experienced the same thing. Other posts I have read say that multi-member LLC's can, but that Turbo Tax does not do so for single member LLCs. One post from 2020 reads:
As TurboTax Expert AndreaC1 found:
TurboTax Business only handles the multi-member LLC, not single-member. If you are using TurboTax Home & Business desktop version or Self-Employed online version, the Form 568 has to be printed and mailed.
