First Year J-1 Research Scholar & J-2 Dependent - Substantial Presence Test?

Hi

 

I am a research scholar and I have been in USA for 243 days in 2019. And I'am working as a volunteer and I don't earn anything. And its my first time coming to USA.

 

My wife has J-2 visa and she has been in USA for 243 days in 2019 also. And she's earning some money. And its also her first time coming to USA.

 

We came to USA together in May,2019 and trying to do our 2019 taxes.

 

My questions are:

1) Is my wife passes substantial presence test?

2) Will she fill 1040-nr or 1040 for residents?

3) And can we fill as married jointly?

4) Should I also fill 1040 and write my income as 0?

5) Can I use TurboTax for our taxes or should we use another one?

 

Thank you for your help.
