If she's reporting a 6-digit Identity Protection PIN (provided by the IRS for certain victims of ID theft), then also be sure she reports the current one. If she had an IP PIN last year for her 2017 return, do not use that one again. If she had one previously, she should have received a new IP PIN in a letter from the IRS in December 2018 or January 2019.
