I filed 1040NR last year. I am eligible to file 1040 this year. I was trying to efile using turbotax, and it asked me for my AGI from last year's 1040/1040A/1040X/1040EZ. I can find my AGI from 1040NR but the option for 1040NR is not listed.

Should I still use the AGI from 1040NR or am I not allowed to efile if I did not file one of 1040/1040A/1040X/1040EZ last year?

Use AGI from 1040NR.
