do u have ur 2018 tax form in front of u? can u see ur agi number? also, there is a prompt while doing ur taxes where it tells u ur 2018 agi. if that doesnt work, request the irs' copy of ur 2018 tax form. if it still doent jive with ur number, i suggest not filing electronically. that way u dont have to submit the agi number. this is also my biggest bane.
