I suspect my return hasn't been received by the IRS; I haven't received delivery confirmation notice from the postal service after a few weeks. I'm filing from abroad.
1. Is there a way to know from the IRS whether they've received it?
2. If I have reason to believe the first return will not be received, should I send another return?
3. Since I'm filing from abroad, I still have the two-month automatic extension, correct?
Thanks!
