This happens just about every year. My 2T computer dies (after having filed my taxes for 2018) and I get a new one...now I cannot access the AGI from 2018 to file 2019 taxes as it doesn't recognize my signin (which has changed from ????) so IRS does not accept my 2019 taxes. I cannot print the taxes from my printer at home and can't copy it from NEW computer to computer at work.
