I was FINALLY able to figure out how TurboTax was calculating my AGI by examining the draft Form 1040 in my draft tax return. First, navigate to the Turbotax Print Center. Then, download your draft return. Finally, look at lines 1-11 to see how TurboTax is breaking down your AGI. This helped me determine what income was and was not being counted, plus what my adjustments were. Hallelujah!
