J1 visa- a resident for tax purposes

I am a J1 holder and my wife is a J2 holder. Based on the substantial presence test, I am considered a resident for tax purposes, so Sprintex has advised me to file my taxes with TurboTax.

I need to mention that I have a social security number, but my wife does not have a social security or ITIN  and is unemployed.

Based on what I've mentioned, can I add my spouse as a dependent on my taxes with TurboTax and do a W7 form for her? Or do I need to file Form 8843 for her?
