Get your taxes done using TurboTax

Apologies - TurboTax cut my question off both in the heading and text.

 

I'm a nomad. My last physical address was in Texas, and that was for 8 yrs. I spent most of 2020 in South America; during this time I had a PO Box in North Carolina that scanned and emailed me my mail. Upon my return to the US, I've lived temporarily in various states -- though never at my own residence, usually at a friend's. I received 1 paycheck to my parent's house in LA (so at least 1 W-2 will have a LA address). Where should I file my state taxes?
