French foreign Dividends & Witholding Tax on split payment

Please advise on how to include foreign dividends received from France in my SA return where Witholding Tax was applied at source (at 12.8%) on only part of the dividend payment (defined as "...represents distributed income") with the balance having no Witholding Tax applied at source and specified as "..a repayment of paid-in capital pursuant to article 112-1 of the French Tax Code"? Please specify the relevant boxes in teh SA return that each figure should be recorded in please. Thank you in advance
