What to enter for last year's AGI when filing jointly

I am filing jointly for 2021 and I also filed jointly with the same spouse in 2020. When e-filing, it's asking for last year's AGI for me and my spouse. Should I type in the same amount from 1040 line 11 for both of us or should I enter 0 for one of us?

 

Edit: we both had income last year.
