How do I code it my self assessment tax payment that I have paid with my business account?

Hello and welcome to the Community, s-thorne-lambbui

We're unable to advise on the specific category to use for tax payments. If you need guidance, please contact your bookkeeper or accountant for best practice. If you don't already have an accountant, you can find a QuickBooks certified accountant near you on our online directory. Thanks. :)
