What is this saying? (Schedule C Worksheet: Amount - Misc Exp Other-39 must be entered.) Where does the 39 or other numbers come from? Is it (-39) or (39)

Schedule C - Other Expenses requires a description for each line on the supplemental schedule. 

Return to your Business Summary page, update Other Common Business Expenses, and update Other Miscellaneous Expenses. Make sure that each line has a description and an amount, even if that amount is 0.
