There are many people explained the difference between the IRS issued IP PIN (6 digits) and the personal PIN you select (5 digits) in TurboTax. As long as you have the personal PIN chosen, you need to make sure your IP PIN (6 digits) is entered correctly in TurboTax. I had the exact same rejection after e-file my fed and state tax after submitted from my TurboTax on Mac.
The fix is to locate the place where to enter the IP PIN in TurboTax. It is not where you enter the 5-digit person PIN for you (and your spouse, if married). The easilest way I found is:
1. Launch TurboTax (your desktop version).
2. While your Turbotax file is open, click on "Search Topics" on the top ribbon bar.
3. In "I'm looking for" field, enter "IP PIN". Click "OK" button to proceed.
4. It takes you to Identity Protection PIN section, under "Other Tax Situations".
5. Under the question "What if my letter says it's for my 2014 taxes?", choose "Yes, at least one of us got an IP PIN."
6. In my case, I only enter my own IP PIN (6-digits) and continue. Of course, if you file jointly, you can enter both your and your spouse's IP PINs.
7. Jump straight to "File" and proceed on all the steps for e-file.
8. After e-file, it shows pending on fed and state taxes. After about 30 minutes, I received a message that my fed tax has been accepted!
It ONLY took me about 3 hours from the first rejection to my final resolution I described above.
