Doubt it was a calculation error. More likely it was a difference in what you entered or where you entered it . All of the tax software undergoes intense scrutiny and approval from the IRS, so the same information entered into any retail tax software program should get the same results. But if you enter some income in a wrong/different spot, leave something out, etc etc etc.....the results will differ. The only way you could spot the difference would be to print the Form 1040's and place them side by side to see what is different--line by line.
