Form 1116 explanation

I am just about finished and the error check produced two items to fix. This one relates to Form 1116 - it says "Check This Entry - Form 1116 (COPY 1) - - Explanation Stm: Detailed Explanation must be completed. Enter your explanation here to complete the required statement. It must show the other deduction items for line 38 column a." I cannot find a line 38 column a on Form 1116 so it is unclear what this explanation is about. Any suggestions would be greatly appreciated.
