Forgot to fill "Total loss to carry forward ..." field in previous year.

I am working on my 2022-23 self-assesment and I realised that on previous year 2021-22 I declared losses as a Sole-Trader but I did not enter the loss amount on the "Total loss to carry forward ..." field . I would like to know If I still can use those losses to set-off my current profits, or I have first to go back and amend the year 2021-22 self-assesment to properly enter the "Total loss to carry forward ..." field. Thanks

Hi djrl,
You would be best placed to amend your 2021/22 tax return first, before setting against your profits for 22/23.
Thank you.
