Hi, I was already two times on J1 visa, work and travel program
Usually I work 4 months and earn around 8000$.

But last year I made mistake with my state tax form, I sent 140 A, and I didn't get any money back, like 150$.

This year I filed 140NR and my standard deductions are 4,373, personal exemptions 2,100 and Arizona taxable income 2,417

But I don't know what I will do with this mistake from last year?

Thanks

You need to amend your 1006 Arizona return and correct the error.
