Thanks for that but it wasn't quite what I needed as the 'is this the final payrun of the year' box hadn't appeared when I did the last payrun. QB live chat helped in advising me to unlock and delete the payrun and change the notification to HMRC to 'in the future' and then back to 'today'. I did that and the tick box appeared.
As a point of note to others if in the same situation, there was no need to delete the payrun, I only needed to unlock it and then finalise with the instruction as above to change the HMRC setting and back again.
