Attaching details of stock and shares losses to self assessment

I need to report trading losses relating to registered shares to offset a capital gains tax liability but the details run to 18 pages of stock and share transactions. The file size is therefore to large to attach online…what should I do please? I’ve reported the total loss on the CGT section and added a note offering to forward the information to HMRC on request ..is this enough?

Hi
You could attach a summary of the 18 pages and include a freehand note, as you suggest, to forward on request if required.
