ADDENDUM
If the above steps don't resolve your issue, go into Forms Mode again, and this time look at the actual Schedule C itself, Part V, miscellaneous expenses. Is there any item there on the actual Schedule C that transferred in from last year that isn't needed this year, or any duplicate entry? i.e., something that wasn't shown on the Schedule C Worksheet? If so, you can try and see if it will let you remove it directly on the Schedule C. If it won't let you, go back to the Sch C Wks or interview and step through to see if you can find it.
Ultimately, everything in all 3 places has to match--the Sched C Worksheet, the Sch C itself, and the interview.
