If you've remitted TDS but cannot download the challan receipt from incometax.gov.in, don't worry. The receipt may arrive via email or mobile message from the tax department within a few hours. You can also check your bank's internet banking under 'Tax Payments' or your payment history on the tax portal to confirm the deduction and retrieve the challan.
Check back in your bank internet banking under Tax Payments if TDS amount is deducted in bank account. It should be there in a few hours if not immediately available.
