It's difficult to troubleshoot your experience in this forum. However, review all your entries to see if you recognize the dollar amount that appears under Schedule K-1 on Page 4. Did you enter any pass-through income from an investment? Did any 1099's you entered include this amount? Do you have any specially allocated items? These are a few possible sources for the entry in question.
Also, if you right-click on the amount in the form and choose "Data Source," you may be able to track down where the amount was originally entered. This may include Form 1065 p1-3 Line 15 or Form 8990.
