1042-S *from another state* when resident alien

Hi,

 

I have a similar question to Where to enter this 1042-S? with a new caveat.

 

I'm a resident of Connecticut (CT) and obtained my green card at the end of last year. I received a small honorarium (3k) from California (CA) which involved remote work and an in-person presentation in CA (stayed there for 4 days). The payers withheld federal and state taxes and sent me a 1042-S.

 

In addition to filing for a federal tax refund as explained in Where to enter this 1042-S?  do I have to file returns for both CA and CT? When I do both, I get a significant tax deduction from CT (4.2k) and I owe taxes in CA (3.5k), is this normal even though I went there for only a few days and earned only 3k? 

 

Thanks!
