Is there anything I can do about the amount of taxes I owe? My boss filed me under married by accident. Now I have to pay a large amount because of it. What should I do?

Me and my boss fixed the issue today his words "whoops looks like I have you under married on here" I have to pay 3700 in federal tax plus 800 in state tax because of that little mistake HE made. I get nothing is fair but is there ANYTHING I can do about this?

No---neither your nor your boss can go backwards in time to change the amount of withholding you had for 2024.   This is unfortunate, because less was withheld from your paychecks during the year if they were withholding as if you were married instead of single.   Your "take home" pay was more---but now you owe.

If you owe tax due, you have to pay it yourself by the filing deadline on April 15, 2025.

 If you have federal tax due you can pay by mailing your payment with the 1040V voucher, (which has the address printed on it, having the payment taken out of a designated bank account, or you can pay directly on the IRS website.

You must pay your state tax due using the state’s preferred method of receiving payment.  For most states that will be by making a payment to the state’s own tax website, or by mailing a check or money order.

You owe the tax you owe.  You got larger paychecks during the year because of the mistake, if you saved it, pull some out of savings.  If you spent it, then sorry, that's on you.  There might (very small chance) something written into your state labor law about this situation, you would have to look that up on your own.

When you file your return, if you can't pay in full, select "I will pay by check or mail" and then go to www.irs.gov/payments to make as large a partial payment as you can.  If you can pay the taxes in less than 6 months, just pay as fast as you can.  If it will take more than 6 months, you can ask for a payment plan at the IRS (there is a non-refundable application fee).  (Don't apply for a payment plan inside turbotax, if that is offered, because the application fee is higher.)

Even if you pay in full, you will probably be assessed a penalty.  Don't pay the penalty up front, wait until you are billed for it.  Then you can ask for a waiver for cause, save your correspondence from your employer to help you ask for the penalty waiver.
