@ Yurika... 1040 EZ is for US citizen and Permanent Resident. Since you are in J1, you are required by US law that you either use 1040NR-EZ or 1040NR. In their website, IRS have clearly indicated by saying "must use this form". "Must" means there are no exceptions.

@deepocean...I have never used Turbo Tax. I use other software like 1040.com etc.
