HMRC VAT Repayment

We do monthly VAT returns as they are always repayments from HMRC, I completed my first VAT return on the system which is a repayment and I need to enter the receipt received from HMRC against the Sales invoice the system raised when completing the return, but it automatically raised it as a HMRC payment showing in the debtors ledger I can't get into it to enter the receipt it goes to the creditors ledger.

Can you please advise.
