Box 14 Code “C” (other self-employment income) on the K-1 isn't used to report ordinary partnership income. It should only appear in limited situations. Based off your initial disclosure of the type of business and activities, I doubt this would be the case.
If the partnership experienced an overall loss for the year, and partners show losses in Box 1 and Box 14A, a positive amount in Box 14C could be a reporting or software error.
If you believe the partnership has made an error on your Schedule K-1, notify the partnership. Ask for a corrected Schedule K-1. Don’t change any items on your copy of Schedule K-1. Be sure that the partnership sends a copy of the corrected Schedule K-1 to the IRS.
