Self assessment ( via Online ) - Change Tax code from 1257L to 1383M

Hi All, I am preparing the "online" self assessment for this year 2022-2023. My tax code was changed from 1257L to 1383M and HMRC has updated their tax record as well. However, during the self assessment, I noticed that the calculation still uses the tax code 1257L (as 'minus Personal Allowance') to calculate, and I can't find the appropriate section to change my tax code. Could anyone please guide me on this?

Hi
Once the Self-Assessment is submitted and processed, the calculation will be updated to include Marriage Allowance if you are eligible.
Thankyou.
