TDS deducted in old pan card

This discussion addresses the challenge of claiming TDS deducted under an old, surrendered PAN card when filing an Income Tax Return (ITR) for the first time with a new, active PAN. The user's client had two PANs, surrendered the old one, and filed their first ITR for AY 2021-22 using the new PAN. The core question is how to claim TDS that was deducted under the inactive, old PAN. While some suggest it might be impossible, the advice leans towards updating the TDS returns with the new PAN and claiming the credit accordingly.
