Sorry yes you do need the 2018 AGI to efile. But since it is rejecting you will have to physically print and mail your return this year. You will not be able to get it to go through.
When did you file last year's 2018 return? Was it Accepted last Year? I can't remember, have you tried using zero for the AGI?
If you can't find the AGI or if it keeps rejecting you will have to mail your return. I would just give up and stop wasting time and driving yourself crazy and mail it to the IRS and state. Why don't you want to mail it?
