QB is asking me to fill in a VAT return for 2 months 1/11/2020 - 31/12/2020 Is this an error or is there a reason for this? My usual VAT accounting period is quarterly?

Hello Glenn Tucker, 

Welcome to the Community page, 

So the start m,onth in VAT settings will be either JAN, April, July or October. If you change it to March, june, September or December it will show the quater for you.
