VAT date correction

SOLVED

Any help with how to rectify this would be very appreciated!

I've just really stupidly run a VAT return for the wrong period (July - Sept 24 instead of April - June 24) and didn't back up the data beforehand, I reconciled the return but haven't filed it with HMRC yet.  The figures are correct (for April to June) as there are no entries in July but obviously the time period is incorrect.  Is there anyway I can rectify this?
