Can anyone help me? I owe the IRS and i dont know where to start. I dont know what to do.

It is important not to ignore your tax and contact the IRS. 

The IRS will let you pay off your federal tax debt in monthly payments through an installment agreement.

If you haven't filed yet, step through the File section of TurboTax until you reach the screen How do you want to pay your federal taxes? Select the installment payment plan option, Continue, and follow the onscreen instructions.

If you already filed, or you're unable to find this option in TurboTax, you can apply for a payment plan at the IRS Payment Plans and Installment Agreements webpage (make sure you've filed your return before applying through their site).
