TDS Refund under 194ia

To file your TDS online, you have to first register yourself on the IT department’s website: https://incometaxindiaefiling.gov.in/.
After registration, you can file your income tax return by downloading the relevant ITR form.
Fill in the requisite details, upload the Form and click on submit.
Upon filing the ITR, an acknowledgement is generated for the ITR submitted, which you must e-verify. You can do e-verification by using a digital signature, an aAadhaar-based OTP or your net banking account.
However, if you haven’t been able to e-verify the ITR, then you can complete the verification by sending a signed physical copy of the same to the IT department
