HMRC Admin 8 Response

Hi, one of the companies I invested in under EIS ceased trading last year and I would like to claim EIS loss relief against my income tax for the 22/23 tax year. Is it possible to do this via the online self assessment portal? I have seen other responses from HMRC in these forums saying it is possible, but it's not clear to me in which section I should fill in the details of the loss. I understand I can use the supplemental SA108 form to claim for this (I think), but again, I'm not clear how this would be logged via the online self assessment process. Can anyone help?
