Filing taxes as UberEats/Doordash worker

Hi I started working full time as a Doordash/UberEats delivery driver this year. Doordash informed me they will send me a 1099 form for tax purposes. This might be a loaded question, but what things regarding paying my taxes do I need to look out for? (quarterly filing, etc.). This is my first time being self-employed and I want to know what to keep track of so I can file my taxes accurately. Thank you!
