Do you use the AGI from your 1040 or the 1040x?

I e-filed 1040 in April and afterwards realized an income document was missed.  So several months later I mailed an amended 1040x.

I'm pretty sure you use the AGI from the Original return

The best way to figure out what the IRS has on file for your AGI since you filed an amendment is to Get Your Transcript and see what they have listed for you.
