Entering my one off pension payment in SA

Hi, Right at the end of the 2023/24 year I made a one of payment to my employer's pension of £5000. This was from my current bank account and so post tax etc. My pension provider has told me they claimed 20% tax relief on that amount. I am a higher rate tax payer. I am not sure about where to enter this amount, I thought it would be "Payments to your employer's scheme which were not deducted from your pay before tax:", will this factor in the fact the provider has claimed 20% relief? Am I also right in thinking the figure I should enter is £6250 ? Thanks in advance, Rob H

Hi robhoney,
You would enter in box 1 on TR4 on main return SA100 Payments to registered pension schemes where basic rate tax relief will be claimed by your pension provider (called ‘relief at source’). Enter the payments and basic rate tax. Yes it would be £6250 that would be entered. 
Thank you.
