Your federal tax refund is determined by the amount of taxable income you are reporting, the taxes owed on the taxable income and the tax payments entered, along with any credit you are eligible for on your tax return.
Look at your Form 1040 Line 11b for your taxable income. Line 12a for the taxes owed. Line 19 for your total tax payments. The federal tax refund is on Line 20.
