This is very confusing: "with only one owner, who receives the only K1 from the company?"

There is no K-1 for operating a sole proprietorship. There is no sole owner of a Partnership. A sole proprietor does not get a K-1 for their own business, because Schedules, such as C, are attachments to Forms, such as 1040. It's not a 1065 or 1120 or 1120S, and there is no K-1 issued from that 1040. And what about the 1099-NEC that was issued to that partner? Is all of the operations performed still considered to be this person's other business activity and not the partnership activity?

This is Sept; it sure seems some of this should have been acted on by now. What all is just now being filed?
