Get your taxes done using TurboTax

With respect to your tax return, "income" just means an item that is required to appear on your tax return.  You likely have certain items of nontaxable income.  "Total income" in the summary is the total of all items of income entered whether taxable or not.  Form 1040 line 9 only includes the taxable portion of your total income (before subtracting any deductions).
