Original vs Derived values

This discussion explores discrepancies between original and derived values in the Tax Information Summary (TIS) for income tax purposes. A user is seeking clarification on whether the Income Tax Department will consider derived values, particularly concerning National Savings Certificate (NSC) interest reported in AIS. They also inquire about assigning income to previous years beyond the standard feedback options. Another user faces issues with inflated dividend values in TIS due to added TCS/TDS, despite correct underlying data, and seeks solutions after unsuccessful grievance attempts.
