Hi Levent Giray,
You declare totals on SA108, boxes 14 to 22 are for listing the number of disposals of 'other property, assets and gains', such as non residential property or assets.
Boxes 23 to 30 are for listed shares and securities and boxes 31 to 44 for unlisted shares and securities.
You will need to decide which are is appropriate for your CFd's.
In the appropriate section, you would show the total number of transactions you made, the total disposal value of all of the assets and the total allowable costs.
Where the allowable costs are greater than the total value, the difference is a loss, which you also declare.
You can include your spreadsheet breakdown as an attachment, to support your losses claim.
