As we don’t have any native payroll on QuickFile it’s not a well covered subject.
Having said that it does pop up on the forum occasionally and the following post explains things in quite a bit of detail.

On QuickFile we track what the PAYE liability is at a given time, i.e. how much do we owe HMRC? QuickFile doesn’t however split everything up, e.g. NI, income tax, SMP etc. This information comes from your Payroll software.
