If you submit the AGI the first time and it is REJECTED,
it will be rejected again the second time and the third time and so on and so on.
If AGI = 0 does not work, start FILE again and say you did not e-File last year.
enter AGI = 0.
If that does not work and you don't have a self-select PIN from last time, you'll have to file a paper return via US Mail.
