@QWJLEGEND , you are correct in that a single member LLC is generally treated as a dis-regarded entity i.e. for tax purposes it is not separate from the owner. However as I mentioned for a Non-US person, there is no-person that take over the LLC identity and therefore it must file a form 8832 to elect to be treated as a self-standing entity -- a C-Corp.
You will have to file both the forms ( 8832 and 1120 ) for the first tax year and thereafter only form 1120 each year .
TurboTax does have TurboTax Business that caters to C-Corp, S-Corp and Partnerships. And you can e-file.
Is there more I can do for you ?
