How can I apply Chinese student $5000 exemption treaty to the federal tax return of the years (2016 and 2017) before 2018?
I have filed the tax return of 2016 and 2017, but I did not apply this treaty at that time. Can I still apply this treaty to the tax return of 2016 and 2017 now? If so, how should I apply the treaty with turbotax? Thanks.
