Hi Bob,
Unfortunately, this forum is for general queries only, we are unable to provide specific advice tailored to individual circumstances, and it is not possible for us to check individual tax records.
You can find information on understanding your Self Assessment tax bill and payments on account here:

To discuss your personal tax situation you can contact us via webchat or our helpline:
Income Tax: general enquiries
On this page you will also see a link to
Personal tax account: sign in or set up which may be the quickest way to review information relating to pay and tax history, tax codes and how to change them.
Thank you.
