twice. My income earned and taxes paid are both showing way too high, exactly by the amount of my bonus. ADP even shows a paystub for the bonus amount twice, one on Dec 30 and one on Dec 31.

I assume I report this to HR, but what happens then? Will I get a corrected W-2? Anybody have that before, how long could that take?

And yes, I confirmed sadly that I was actually only paid the bonus once.
