You can enable TDS invoicing to this client by following the steps:
Once modified, make sure that the TDS Type you're selecting is correct in the client's invoice. You can enter the TDS amount applicable to that invoice (10% or 7.5%).
Also, I've got this handy article to learn more about enabling TDS to customers and suppliers: How to set up TDS.
Then you can run TDS reports available in QuickBooks Online like TDS Payable Report and TDS Receivable by following the instructions from the given article above.
