Hi Clelio De Souza,
Based on the years you have mentioned and without having access to your wife’s account, the earlier years may need a slightly different process to be updated onto her record. It may also be if the payments were made separately and not in one lump sum, that they have been actioned at different times.
However, if at the time of receiving your reply from us, your wife's account is still showing this, it would be advisable to contact our National Insurance team so that we can check that the payments for you.
National Insurance: general enquiries
If you call on behalf of your wife, she would need to be present to complete our security questions before we could give you any information
Thank you.
