Where can I find my AGI?

Excuse me, could you possibly clarify where exactly I can locate my Adjusted Gross Income, or AGI, for tax purposes? I've been searching high and low, but I'm having difficulty pinpointing the exact document or source where this information is typically found. Is it on a specific tax form? Or perhaps there's a dedicated section within my online tax filing account? I'd really appreciate any guidance you could offer in this matter.
