If using software (not doing thru online account) and after being rejected, you can go back to file and click:
FEDERAL TAXES -> Other Tax Situations
look for "Other Return Info" section & press START. Go thru the questions and you will need to enter the IP PIN (6 digit) for all listed in the filing if applicable, if only 1 person has IP PIN then only that person IP PIN is entered.
TurboTax still will request the 5 digit personal pin. The IP PIN (6 digits) will be stored separately in section VII.
