I understand and agree. I am not doing any other calculations other than comparing the line 3 amount on the Social Security worksheet with the total of the numbers used from the 1040. The amount entered by TurboTax on line 3 is $693 lower than just the 1099-INT and 1099-DIV as reported by Schwab to the IRS. Lines 4b and 5b represent another $2,565 in taxable income that is not being included. I got tripped up once before when the IRS sent me an inquiry when one line on Schedule B reported by Schwab to the IRS differed from my entry on my 1040. I'm just trying to avoid another "surprise letter".
