IND-031-04 rejection code - Practitioner used last year

I am doing 2023 taxes this year for a family member who is now in a nursing home.  Last year she used a Practitioner to do hers. On the form 8879, he was authorized to generate a pin for her. On the same form, he generated an ERO's EFIN/PIN for himself.

My e-file for 2023 keeps getting rejected by the IRS.  I have put in last year's AGI from line 11.  I have used the last 5 digits of the practitioner's EFIN/PIN. I have tried using her generated pin (which of course is different than his pin.)

How can I resolve this issue so the IRS will accept the e-file?

Thank you,
