457b federal vs State Amount

My 2023 W-2  from Empower shows a different amount in Box 1 Federal wages compared to Box 16  State wages. My understanding that the difference relates to PA guidance related to the sum of original deferred compensation and the earnings on that amount and how distributions are ultimately paid out. The Plan administrator stands by the lower state amount but cannot (will not) provide a PA Tax reference or details of the calculation. Meanwhile TurboTax is stuck in an endless loop preventing me from filing the return electronically while there is a difference between these two amounts on the w-2. Does anyone know how to get past this or do I have to file by mail?
