Is there another way to get my tax information from last year?

For my taxes this year, I was told I would need my return and/or AGI from last year. Well last year my now ex-wife did our taxes so she has all the information and won’t give it to me because she hates me and told me to give her money for it (screw that). So does that mean I won’t be able to do them or is there another way to get my tax information from last year? Thank you.
