I finally decided to e-file my taxes. The IRS rejected my return, saying they couldn't confirm my identity. I tried to get a PIN online. It said they couldn't confirm my identity.
I called. They said I answered the questions wrong. I waited fiften minutes to speak to a supervisor and was disconected.
I called back and finally got through.
The problem was they had my address as 410 instead of 401. Their fault completely...and it was what caused the whole problem.
