You need your 2018 AGI to e-file your 2019 return. That AGI is how the IRS verifies your identity as the same person who filed using the same Social Security number for 2018 and 2019. If you cannot find your return you can get a transcript from the IRS or you can try using zero. If zero does not let you e-file you will have to print sign and mail your 2019 return.
