But it looks like it is asking me to repay it via 2 payment on accounts when I assume I have already paid this underpayment during my 2021/2022 employment, no? Why do I need to pay it twice?

Hi, I noticed this line in my self assessment. I worked in 2021/2022. Surely I have been paying this underpaid tax through my tax code in 2021 and 2022, no? Why do I need to pay again this underpaid tax?
