I'm working on the MA tax return. I need to enter the non-MA portion of the amount I paid to FICA. Do I enter the same amt in the All States column or zero?

Neither. Enter the amount of FICA tax you paid until September 13. Massachusetts taxed remote workers until September 13, 

 

"After September 13, compensation earned by non-resident employees will be sourced based on where they actually work, regardless of where they worked prior to the COVID emergency," Massachusetts said.

 

Multiple your W-2 Box 3 Social Security wages to September 13 by 6.2% and your Box 5 Medicare wages and tips by 1.45% for the Non-MA Portion.
