Oh okay, thank you. Sorry for the confusion, I meant to say "supposed to be correct" when I was trying to determine how to estimate it regarding the side gig job (staffing agency). Okay then since the Tax Withholding Estimator resulted in $0, I guess it will be estimated around that time, because I also plan to work a full-time job this fall season. So for a new w-4 form, my circumstances will change job wise by then.
