Hi Amoramas1,
If you have filed for an incorrect period within QuickBooks Online, you would need to make a request to have this period unfiled.
This would need to be done by giving our Care team a call and providing us with details in order for us to do this and open up the VAT filing period so that you may submit for the correct dates.
For our contact details and opening hours, please visit our Contact Us page.
Let me know if you have any further queries
