Estimated tax you owe (this year)

I received a tax code notice adjusting my tax code for 22/23 to reflect estimated tax owed for that tax year and which was collected by 5 April 2023. Do I need to include this at box 7 of my self assessment return (which states "Underpaid tax for earlier years included in your tax code for 2022–23 – enter the amount shown as ‘amount of underpaid tax for earlier years’ from your P2)? I assume not as is an estimate only and does not relate to earlier years, just 22/23, but grateful for any advice.

Hi shof34321,
No, as from what you have stated it was an in year adjustment and not taxed owed from an ealrier year.
Thank you.
