Hello, I've been dealing with this problem as well. I need my AGI from 2018 to file my 2019 taxes and get my return done AND get my stimulus check.
My IRS online verification fails and its failed with Verizon wireless, Cricket & T mobile. ALL are in my name and my names on the caller ID and CNAM lookup tool. All of that is meaningless when it comes to the IRS validation process.
