1099 and W2 Employee (Multiple Jobs)

I am currently working 3 part-time jobs. For two of the positions, I am 1099 and hold similar job roles & duties. I also work part-time with a company as a W-2 Employee. I am wondering about the best practice for filing quarterly taxes. Do I just consider my 1099 positions? I have made roughly $25,000 just in 1099 this year. 

 

I keep track of my 1099 income and estimated taxes owed in a spreadsheet, along with my expenses which I track separately. I know the form I am supposed to use to estimate these numbers, but I feel nervous. I have not yet filed quarterly this year so I know I need to do so at the upcoming quarterly due date for all previous quarters. What if with my expenses I owe nothing according to the calculations? Is that ok? Can I file quarterly on Turbo Tax?
