Do I deduct payments on account made in Jan and July 2023 from tax the due for 2023/24?

Hello, I am confused about the payments on account. Last year (Jan 2023) I paid the full amount shown on my self assessment tax return calculation for 2022/23 plus 50% on account which I understand to be a payment towards the tax that will be due for 2023/24. I also paid a further 50% in July 2023 which I believe also goes towards the tax due for 2023/4. So when I do my tax return this January do I deduct the amount already paid last year and pay the balance due for 2023/24 plus 50% in advance for 2024/25? Thank you.

Hi,
You do not declare the payments on account on your Self Assessment tax return.
Once your Self Assessment tax return is filed the payments on account will be allocated against the balance due on your statement of account. 
Thankyou.
