<<It is also not clear how you could have ended up with negative adjusted
gross income, based on the information you gave us. Your excludable
foreign earned income must be added into your gross income before it can
be excluded. After your excludable foreign earned income has been
reported on your Form 1040 on line 7 or 12, and then subtracted on line 21,
your remaining adjusted gross income should reflect your US earned
income, your interest and 1099B income.>>

Ignoring for a moment the remainder of the unclear issues in the e-mail from the IRS, this is exactly what I and LoTax were trying to point out to you. You must first add all of your income, then remove the foreign earned income. The difference would be your US income...which would also be your AGI (ignoring any other adjustments of course). If you are arriving at a negative AGI, that would indicate that you have other non-foreign losses somewhere else on your tax return. You add...you subtract...you arrive at zero.

So without going line by line on your tax return, it's really impossible to tell you why you are arriving at a negative AGI, nor is it possible to lead you in the right direction relative to turbotax.

Sorry...but there is just nothing here that I can help you with...
