Business & farm

The K-1s I just did for a business are showing the correct amount of taxable income in 14a and some very incorrect amount in 14c.  What should I tell the customer to use on their personal return?  They are going to ask why there is an almost double amount of taxable income in 14c.  I read that you answered it has to do with nonfarm income.... what?  These are two partners in an LLC and we should be treating their profits as self employed income.  I cannot even reconcile the amount showing in 14c.

Please answer quickly if you can

Thanks!
