Marriage allowance

Hi HMRC, I and my wife submit Self-assessment for 2022-2023. Since I hope my wife transfer the GBP1260 allowance to me, my wife have submitted the marriage allowance in Sep 2023 and received the email been approved. However, when I submitted the self assessment for 2022-23, I found the personal allowance amount did nor increase. Would you mind tell me any problem for the system or my procedures ? Or Should I need to stated the GBP1260 allowance in my self assessment fill in process ? Which section box should fill in ? Thanks

Hi pennyhm Cheng,
If you are the recipient of the marriage allowance transfer then you do not enter any details on the tax return.
Once submitted our systems will pick up that you receive the transfer and your Self Assessment calculation will be amended to include this. 
Thank you.
