Are you saying your ACTUAL income tax return - the one you printed out before filing so you could thoroughly review it before sending it to the IRS - showed an amount owed of $0? OR, are you really talking about the "Refund-O-Meter" at the top of the page? If it's the latter then print out your actual income tax return and look at that. You don't file an income tax return and judge its correctness or otherwise by looking at the "Refund-O-Meter".
You don't cite anything to support your belief that what caused the change is due to "negated my bona fide foreign residency" so look at your ACTUAL income tax return and figure out what, if anything, is really going on.

So you should at this point be able to make changes - like that removed 1099 - and look at the "before" and "after" versions of your income tax return to determine what's happening.
