You've found the right article from the www.gov.uk website, rjwbailey. That's what we actually recommend if an employer noticed that they underpaid an employee in the previous pay run.
We have an article about deleting pay run in QB Standard payroll, and we've emphasised in there that if you're trying to delete a submitted pay run to correct it, just leave it and apply the correction in the next paycheque instead. It's the second statement in the Things to know section.
I know you're looking for articles. Feel free to check out the Standard Payroll Hub. We've compiled some useful articles there that you can use as reference in the future.
