Good day @calchas63,
I'm here to lend you a hand and provide the steps you need to clear this prior VAT return.
If I understand this right, it's supposed to be a paid and filed VAT return. If so, we'll need to enter this payment by hand.
Let me show you how:
This will clear your prior VAT return showing that it's filed but not yet paid.
If you've already signed up for Making Tax Digital (MTD), you can refer to this article on how to submit a VAT return to HMRC. It shows you the updated way of submitting your VAT online.
For any other questions or clarifications, don't hesitate to leave a comment below. Anyone of us here will be glad to assist you.
