Filing joint return, getting rejected for spouse AGI but we filed Joint last year, and Joint this year. I try PIN, but I find no space for Spouse PIN, only my pin.

Make sure you are using the same AGI number for both of you since you did file Married Filing Joint last year. 

Also, if you've been rejected for the AGI, it is best to go directly to that area yourself to start from the beginning of Step 3 under Filing.  Sometimes that clears up any wrong information.
