Pension lump sum on french tax forms

[S8J]

Hi all,

I know I declare a small lump sum pension payment on form 2047 line 11 but what is the difference between pensions, retraites line 1al/1am and pensions de retraite versées en capital Line 1at.

Also do I include in the sum the tax deducted by the uk which has since been refunded.

Hope someone can help as thought I understood when I asked last year at the tax office but now I have to complete the forms I'm not sure.

Cheers
