IRS does not recognize my mother's pin#

[LisaVee]

My mother has a pin number for filing her taxes online with Turbo Tax.  However, the past two years (2018 & 2019) she owed money and did not want to file online. She wanted to paper file once we had completed the return and printed it.  This brings us to the 2020 filing season.  We are trying to file her Federal return online this year and it  keeps getting rejected.  The reason for the rejection is either the 2019 AGI amount (which is correct) or the PIN number.  The pin number is the same number she used in 2017.  Does she have to get a new PIN or What?  Your comments and suggestions are appreciated.
