Deductions & credits

Refund and tax due amounts do not change in the return after the return is filed - it's not possible, Perhaps you saw the combined state and federal refund,and are now seeing only the federal.  Or, perhaps you saw a refund amount before you finalized your return.  If you are referring to a change made by the IRS after you filed, that happens often due to information missing or being incorrect in the return.
