Why does it matter?
Download a Record of Account Transcript now, if you have not already done so. After your amended return has been processed, download another Record of Account Transcript. Then you can tell us the answer. (Post the answer here in this thread, not a new thread, to complete the discussion and to make sure that anyone participating in this thread or following it will see the answer.)
A Record of Account Transcript is a combination of a Tax Return Transcript and a Tax Account Transcript. The Record of Account Transcript shows AGI in two different places. You have to clarify which one you are looking at.
I don't have a definite answer to your question, but the first AGI, at the top of the Record of Account Transcript, is under the heading "Information From The Return Or As Adjusted." That strongly suggests that it will reflect the adjustment from the amended return. The other AGI is in the Tax Return Transcript section. A Tax Return Transcript always contains the information from the original return. It does not get updated when an amended return is processed.
