Overpaid Voluntary Contribution

I mistakenly paid £5 more than I should when making a Voluntary Contribution to fill Gaps in my NI record. How does this affect my record. Will it still be allocated to my record and fill a gap as it is an overpayment. Or is there anything I need to do? I was to pay £824.20 and paid £829.20.

Hi
Our International Team will use £824.40 to allocate a tax year to your National Insurance account and the overpayment of £5 should be deducted from your next payment of voluntary contributions.
