I filed VAT in QB for Nov-Dec 18.  It correctly created a creditor for when it was paid.  Someone else was working on the file and when I went to look at this return there were no previous returns filed and the creditor is gone.  I have no idea what happened.  The period is warning as closed when post an invoice into Dec 18 because of this file VAT.  Is there any way of rectifying this?  Thanks.
