Requesting a overpayment from 22/23 tax year

I have just completed my 22/23 self assessment tax return. For the first time when showing an overpayment I have been requested to wait 72 hours before claiming a repayment. I have waited a week but still cannot see where I can request a repayment. On my tax return, it showing as a 2022-23 balancing credit. Does this mean it will be taken off my PAYE tax coding for 23/24?

Hi
If you are unable to request the repayment online you will need to contact our Self Assessment department so that we can look into this for you.
