Let me walk you through the steps on how to send a VAT report to HMRC.
Go to Taxes.
Select VAT.
To view your open return, choose Submit return.
Make sure the dates and figures are correct.
Click the File online with HMRC to submit your VAT return to HMRC.
Enter your Government Gateway User ID and Government Gateway Password.
Select Yes, I want to proceed.
QuickBooks will now connect to HMRC to submit your VAT return. When the HMRC receives your VAT return, you will see the message "Your return has landed safely". You can now click the Close button and continue working.
