Loss carried forward confusion

Hello! I'm helping with a tax return and need some advice around loss brought forward. 2019/2020 taxable income was around £17k 2020/2021 tax year there were zero trade profits or taxable income - besides SEISS of around £10k (live events shut down) 2021/2022 taxable income £29k with £6k SEISS How do we calculate what to bring forward and where does it need to go? I know that loss should help reduce taxes this year, but we're struggling to find exactly this scenario, so any help would be massively appreciated. Thank you kindly in advance!
