Do I remove AZ or leave both unchecked? Live in AZ, filing non-resident for MA

[almargahi]

I am filing a non-resident return for MA due to some RSU vesting from when I lived in MA 3 years ago. This question that asks to remove wages that are 'duplicate and not from Massachusetts'. Does it simply mean to check the AZ one to remove it? But what about the word 'duplicate', I don't see anything duplicate in here.

Yes, you want to remove the Arizona wages because they will not be taxed by Massachusetts.
