An IRS supervisor told me that 2019 taxes took all of 2020 to process from delays caused by the pandemic restrictions. Many 2019 tax returns were not in the system at the start of 2020 so there was no 2019 AGI to verify for the 2020 e-filing, i.e. nothing to match it against. A prior year recommendation said to try replacing the prior year AGI response with $0. I tried that after my 2020 submission was rejected. I received a preliminary "accepted" response from TurboTax and just now received a notice that it was accepted by the IRS.
