Challan corrections are possible even after 7 days. Within 7 days, approach the bank branch directly. After 7 days, log in to the income tax e-filing portal under Services > Challan Correction to request a minor head change (moving the amount from surcharge to interest). One thing to also check: from April 1, 2026, the Income Tax Act 2025 uses new TDS section codes in challans, and a mismatch in section or minor head can cause reconciliation issues in TRACES. This [section mapping guide for FY 2026-27](https://taxgarden.in/blog/income-tax-act-2025-section-mapping-old-vs-new-india) shows the correct codes to use going forward.
