I have to check the Form 1116 COPY1 - Foregin Tax Credit Comp Wks. But I do not understand what I should check!

Form 1116 (COPY 1) -- Foreign Tax Crdit Comp Wks: Total Incoming C/O has a vlaue. This will require Form 1116, Schedule B, which will be available in a future product update.
What should check I in this entry?
