Do I need to submit Form 15CA?

Hello, I stay as a tenant and my landlord is a Non-Resident Indian. Every month since the start of the current fiscal year, I have been transferring the rent from my savings account to his NRO account. The yearly rental amount will not exceed INR 5 lakhs. Kindly advise if I need to submit Form 15 CA in this case. If yes, then what should be the RBI code and the sub-code.

Thank you.
