Question 1) If a US expat in foreign country is self employed as sole proprietorship (in other words, without any separate entity like corporation or limited company etc), can he / she still show this in schedule C as if he lived in the US? In other words, the schedule C is only for people in the US, or, US citizens living in foreign countries can also use it?
If the answer to question 1 is positive:
Question 2)
Does Turbo tax allow such use, or it forces / wants a US address to fill schedule C? Or we fill nothing and the primary foreign address is automatically written there or the address is left blank, since we show the primary foreign address on 1040 anyway - and the tax return can still be efiled? Or turbo tax doesn't allow US expats with foreign addresses to use schedule C but it is ok to print and mail the tax return ourselves?
