This discussion addresses an issue where an individual filed ITR-1 correctly according to their 26AS, but received an outstanding demand notice under section 143(1) citing lower TDS deduction. The user had already submitted a rechecking request and was seeking further steps if no response was received. Suggestions included verifying TDS schedules, TAN numbers, and checking the 'Tax Credit Mismatch' under the services menu before filing a rectification return.
