You can find it on your 2018 1040 but you do not need to file your 2019 tax return--if that is why you are looking for it. You only need that 2018 AGI in order to e-file 2019. E-filing closed for 2019 weeks ago and now the only way to file 2019 is by mail--which does not require that AGI to be entered.
