AGI from 1040-NR-EZ

I filled my taxes using 1040-NR-EZ form using Sprintax. But this year my tax status changed, so I am using turbotax.
However, when I am trying to "File" my taxes, I am asked to choose between the tax return forms I used last year. Options are as follows: 1040, 1040 NR, 1040 X or 'I have my return transcript.' Which option should I choose?
