TDS late credit

Hi,

We have filed ITR for FY 2022-23 in the month of September 23 and got the refund in the month of November 23. The TDS payment from one of the clients was pending and we pushed them to make the payment in the month of August 23. After getting the assurance from the client that they will be depositing the TDS, we went ahead for filing the returns in September 23. 

The problem is that we got incorrect refund since the TDS credited from the same client wasn't reflecting in the 26AS until we received the refund. We again pushed the client to check on this and from the very next day we got  form 16A from the same client and TDS amount is now reflecting in the form 26AS.

Now how to get this amount as this is supposed to be a refund? What is the time span required for the process?

Thanks in advance,
