Thank you, @ErnieS0 , for your detailed response.
I've been living in California only, and Arizona was just an example of state that they say no double taxation happens for selling the real estate in Korea.
Regardless, the main point of my question was if TurboTax (version: Self-Employed Online) is good enough to handle those things given the fact that it should understand tax treaty b/w US and a foreign country and the difference in handling the tax per state. I assumed yes, but would like to confirm.
If TurboTax is not good enough, I need to find a CPA asap. Thank you.
