Get your taxes done using TurboTax

You did not already "pay tax". What you paid was only withholding, an estimate of the tax  due. No piece of income is taxed individually. All your income, including pension plan & IRA distributions, is added together at tax filing time. The tax is calculated on that total (after adjustments, deductions, and credits). Then withholding is subtracted to determine if you owe more or get a refund.
