God! I run into the same problem you had, but now is 2025!!! Just found TurboTax for Business still does not support LLC with Non-resident members who need 1042s!!! That means they did nothing in these 3 years to improve their software since you reported!!!
If you see my msg, could you tell me what you did for you LLC filing? Did you file 1042s ONLY for the payments which need the withholding? Or for every kinds of payments, that would 20 to 30 1042s forms that I need to fill out?
