Three questions/1099 Doordash/Ubereats

Hello,

#1. I am an independent contractor for Uber Eats and Doordash. It is my sole income temporarily.  I do not earn much. Can I  pay my taxes in April of 2025 when I file for 2024? I will only get one form. They do not send one for quarterly taxes, or at least I haven't gotten one. Maybe because I earn a low amount.  

#2. If I am required to pay quarterly taxes, what should I do if I don't have the amount I need to pay? How will that work out?

#3. How would I find out what I owe, considering I only get one 1099 per year?

Thank you
