How to prepare for taxes from income earned through shopping app (Shipt, Instacart, etc.)

Hello! 
I have been working as a shopper for an app and as this am an independent contractor. How do I prepare for taxes? What receipts, mileage, gas, etc. should I be setting aside? How much should I prepare to remove? I began January 2022 and am lost as to what is and isn’t needed.
