Quarterly Estimated Taxes Question

Hello! I've been using Turbo Tax for a number of years and have been employed by companies usually; now for the last two years being a mix of freelancer/employed. I haven't made enough to worry about quarterly, but my estimate for what I will make through the year of 2022 (as just a freelancer), might warrant quarterly filing.

 

But I'm so confused, I paid in full all I owed for 2021.

 

Do I pay quarterly taxes for what I earn in 2022, during the year of 2022? 

 

Or 2023? 

 

Can I also pay quarterly as a mix of two 'industries'? I'm a sole proprietor who does dog walking and graphic design to get by. 

 

Thank you!
