Wrong lower deduction certificate used in TDS returns

A user mistakenly used an expired lower deduction certificate in their TDS returns, resulting in a demand for short deduction. After paying the demand, they wish to rectify the return on Traces using the correct, valid certificate. The advice given is to file an online correction on Traces, specifically by adding or modifying the deductee row, highlighting the incorrect entry, and updating the certificate number before saving and processing.
