Sure...but check a couple things first
1) If you filed on paper last year enter a zero for your AGI
2) If you amended your tax return last year, you have to use the AGI that was on your ORIGINAL first-filed tax return, not the amended one.
e-filing anywhere else will also require your AGI...unless you go to a tax preparer (maybe).
