Thank you for this confirmation. Can you advise how I would do so, is it via submitting a self-assessment return?

I have receive a notice from HMRC advising that I have underpaid income tax in 2023/4 due to part of my personal allowance having been lost due to my gross income being greater than £100k. I have made pension contributions in the year to a workplace pension scheme which operates under a "relief at source" scheme. These have not been deducted from my gross income as they do not appear on my P60. Am I correct in assuming that these "relief at source" pension contributions should be deducted to calculate my adjusted net income for personal allowance calculation purposes? If so how do I do communicate this to HMRC? Thank you.
