It would be unlikely you’d owe them a whole lot considering it’s already mid September.
You can change your W-4 and bank info whenever by going to OneWalmart and searching “W4”, and “Direct Deposit”.
Even if you don’t do the w4 it still takes taxes out. Not sure what the default w4 is though
Default is usually single with 0 dependents IIRC. Since you have to declare your marital status and number of dependents, payroll doesn't assume anything more if you don't fill one out. It takes the max amount out of your earnings.
Better to have too much taken out, and end up with a possible refund, than take out too little and end up paying in at the end of the year.
Edit: changed less to more
