I have a Partnership LLC and received K- forms for both my wife and myself. That information was entered under 'Personal Income - Schedule K-1". The information was also entered "Business Income and Expenses - Schedule C"
Are they supposed to be entered twice?
Did you file a partnership return? If so, then you will only enter the K-1's for you and your wife. If you did not file a partnership return, then each of you enter your share of income/expenses under schedule C.
