I had a similar issue of multiple rejections due to the error of AGI not matching although it is exactly what I had from last year's returns. I am submitting from outside the USA so when I tried to get an IRS Transcript it does not work for outside the US as someone else mentioned.
The issue may be due to my late filing last year by mail and not efile. So maybe IRS still does not have my 2018 AGI on record !!??:
Now Turbo Tax is telling me that " The Return has been transmitted" - Do I still print my Tax Returns and send through mail ???
