@dixie This is an option. In order to activate Statement C and see it included with forms in use, you'll need to link the QBI Statement C information worksheet to the pass through entity's K-1 entry worksheet . First, from the forms menu, select "K-1 stmnt C  entry" and enter the applicable entries. Next, you'll need to link the statement C  worksheet to the K-1 from the pass through entity.  You'll find the linking option near the bottom of the K-1 Partner worksheet after the  Section A Qualified Business Income Deduction - Statement A Information. Right underneath the Section A entries there is a field that you must double click to link the Statement C QBI information. Once statement C is linked, you will see it with the forms in use on the left hand side of your screen and when you print your return. 

If statement C still isn't printing with the return after completing the steps above, check your global print options. To do this, select the print icon, then "global print options," then "Control Which Forms Print."  If you expand the subcategory "Statements, etc. (filed with return)" you will find options for including the 199A Statement C summary. From here, you may decide which forms print with your filing returns.

I hope this helps.
