VAT error on AR adjustment
I had a list of debtors which includes several that owe zero. One in particular had several entries adding up to zero balance. There was a journal covering these. I used the make payment function to allocate the payment and deleted a journal which had been set up to zero the account. Now the account is still zero but the VAT on the transactions is appearing on the current liability, yet the VAT would have been included on the relevant VAT return 6 years ago when the account was active.
I know I've messed up, but I need to get that £3k off the VAT liability before November! I've only been in the role a few months and not used to QB. Can anyone suggest how to get this back how it was? Thanks
