Emergency tax code on my work pension

I have just recently retired and I'm receiving my work pension but I have no other income, but I have an emergency tax code which is taking far more than it should. How long will this continue it states on my profile on HMRC that I have retired from my employee so they are aware. Very confused tbh.

Hi,
Unfortunately, it is not possible to check individual tax records through this forum. If you have a question which relates to your personal tax situation or tax code please contact our Income Tax team.

On this page you will also see a link to Personal tax account which may be the quickest way to review information relating to pay and tax history, tax codes and how to change them.
Thank you.
