I am regularly filing e-tds return, till Q3 FY 2022-23 csi file was downloaded from NSDL OLTAS and it was fine.   

In Q4  FY 2022-23 I am unable to download combined Jan Feb Mar 2023 csi file as paid TDS challan  for Jan and Feb 2023 are available on NSDL OLTAS portal and for Mar 2023 is available on Income Tax portal.   How to club these csi file to upload Q4 Form 26Q TDS return for FY 2022-23.

Thanks in advance
