The IRS said "the limit of e-file attempts with an incorrect 2018 AGI has been used file by mail" I don't have a printer and I messed up my agi a few times bc I didn't understand how to calculate i

Feel free to give it one more try and if you are still unable to e-file after correcting your AGI, check with your local library, or perhaps a family member or a friend to print your return so you can mail it off.
