For AY 2020-21, Self Assessment Tax Payment [ITNS 280 -> 0021 -> 300] was made on OLTAS via Netbanking on 12Jun2020 and amount was immediately debited from bank accnt and also got Taxpayer Counterfoil. As of now (19Jun) TIN NSDL Site Challan Status Equiry says Receeived by TIN On -> 15-06-2020. Also indicates "Amount Matched". But as on 19Jun2020 Form 26AS is not updated to give me credit for this Tax paid. Is there a problem in TIN site? Will it get resolved on its own? How long shoulld I wait before initiating any action? Whom should I contact for this issue? (Earlier, few days before, had earlied paid similar SA Tax and it has appeared OK in 26AS.)
