State tax filing

Hi 

I am still a bit unclear on why I can file may Federal and NJ State taxes electronically but I cannot file my NYS Non-Resident tax electronically.  We file married joint but I work only in NYC and my husband and I live in NJ and he works only in NJ. Is it because it's non-resident? It's quite maddening to me.

Thanks to anyone who can give me a real reason why in 2020 this is still an issue.
