if you filed joint in 2018 you may be able to access a transcript of your 2018 return which will have the agi.

or if you prepared the '18 return using TT you should be able to acccess it but if he did then not.

You can login or create an account on the website, or call the IRS, and get a transcript of your return from last year.
