Are you sure, because when entering k-1 for federal return it asks to 'Enter Percentage of Ownership from Box F' with instructions saying 'Tell us your percentage of ownership, as shown in Box F on the Schedule K-1' which is not available form K-1 (100S), shareholders percentage on form 100s is on line A there is no Box F, that info only matches what's available on Schedule K-1 (Form 1120S). If I understand Schedule K-1 (1120S) is for federal and (100s) is for state as it says California Schedule K-1 (100S).
