"IRS says my tax return has not been processed"
If you're referring to the "Where's My Refund" tool, what is the exact terminology at the IRS website?
http://www.irs.gov/Refunds
It doesn't use the phrase " has not been processed." Does it say your return is still being processed? Or does it not find your information?
If it says it's still being processed, we can tell you how to phone the IRS to inquire on it. And if you don't get good info from the IRS, or continued delays, how to contact the IRS Taxpayer Advocate Service for possible assistance.
