Final Income Tax bill on deceased's estate

Hi, My mother died last year and I'm the executor of her estate. I got a tax refund soon after she died, but then a few weeks later I got a request to repay the last week of State Pension that she received after her death, about £200, which I paid. Should I be due a further tax refund on this money? The first refund came through so quickly and I thought the £40 might come after April, but nothing has arrived.

Hi,
I'm sorry for your loss.
To give you the best advice, we may need to review your mother's account.
