How do I get full refund of SUI/SDI/FLI taxes from NJ?

I'm working and residing in Texas. My employer wrongly tagged me to NJ and deducted taxes for UI, DI & FLI for a few months in 2019. I understand that I can file a non-resident return and get a refund on the NJ state tax, but how do I get a full refund of SUI/SDI/FLI taxes from NJ? What is the procedure? Appreciate your help.
