If I had chosen the 2(b) table option on the W-4, it would've been taking approximately $580 per pay period, instead only $180 has been taken out in each pay period, leaving us with an estimated shortfall of $12.5k in owed taxes. Can we simply pay this estimate to the IRS now via their only payment? I cannot for the life of me reach anyone at the IRS to help answer this question.
