Filing my taxes for the first time: How to handle payments i got via Zelle for independent work?

I recently moved to the U.S. with a green card. Due to limited grant funding and a slow hiring market, I’ve been doing remote gigs (e.g., teaching medical students), and I’ve been paid via Zelle.

I’m now preparing to file my tax return and want to make sure everything is clean and properly documented.

Do I simply report the total amount I earned, or do I need to provide additional details or proof of income?
