When I filed tax return using Turbotax last year, I was still an F-1 student (started F-1 in 2010) and I did not realize I could not use this website. I succeeded at getting the tax return. Do I need to do anything now to fix the mistake and supplement necessary docs? I have already filed tax return for 2016 this year but I am a permanent resident now. Am I allowed to use Turbotax?
