I received a CP01A that included my PIN which is 6 digits. The TurboTax software however is only allowing me to enter a 5 digit PIN. Why is this?

Because you are in the wrong part of the interview.   The 6-digit IP PIN is entered in another interview topic.  

The IP PIN (Identity Protection PIN) is a 6-digit PIN provided by the IRS to certain victims of ID theft.  I'll provide 2 methods to get to the proper entry screen,

Here's how to navigate to enter the IP PIN into TurboTax:

• Log in and open your return ("Take me to my return.")
• Once the return is open click in the top right corner on SEARCH.
• Enter IP PIN without quotes.
• Choose Jump to IP PIN.

Or here's an alternate navigation:

• Federal Taxes tab.
• Subtab Other Tax Situations
• Scroll down to Other Return Info.
• Choose Identity Protection PIN and Start (or Revisit.)

This worked to get me to the correct place to enter the 6 digit PIN, however in the final review it sees the empty 5 digit PIN box as an error.  NEVER MIND, it's a Self Select number! (I finally read it!)
