Credit Limit worksheet

In reviewing my forms (via print to PDF), I printed all forms, I found on form 8812 if references "Credit Limit Worksheet" a number of times.  On line 14c it instructs you to put the amount from Credit Limit Worksheet A.  I am trying to find that work sheet.  I have gone through the printing to try and select certain forms, it is not listed.  I have printed all forms and walked through the whole report and it is not there.  I have gone through tools options, view forms, etc. and find no evidence of where this amount came from.  I have searched help files and google and have not come up with a good answer.  Any help would be appreciated.
