W4 filed wrong at work

So frustrated, I filled my form 0 and additional 30$ every paycheck to federal taxes. With the way my paystub looks under “federal taxes” I’d always consistently 160+ . Apparently my jobs pay accounts add in all federal, medical, social security into the amount that shows “federal taxes” which is why it was always showing over 100 to federal taxes.

My job somehow processed my form as only taking 30$ out biweekly. Only 700$ for the year taken out for federal taxes.

I asked my hr department where the disconnect happened and I haven’t received a response. Looking at paying in 2,800$ now to the irs.

Just frustrated, I’m setting up the payment account but ughh
