You are using the wrong PIN. You do not use your IDMe pin to e-file.
Did you request an IP PIN ---it is a six digit number.

If you have a 6 digit PIN issued to you by the IRS you need to enter it in order to e-file. Go to Federal>Other Tax Situations>Other Return Info>Identity Protection PIN and enter the six-digit PIN.
