If you owe taxes from a prior year, any refunds from your current or future tax returns will be used to pay back the IRS. Any remaining refund would be sent to you.
If you're unable to pay the taxes due on your current return, the
IRS offers installment agreements to allow taxpayers to pay tax due over a
period of time. You may complete the form in TurboTax and submit with your
return (Can I file a Form
9465 (Installment Agreement Request) in TurboTax?). Or you may file your
return and wait for the IRS to contact you regarding the tax due, which will
include information about Payment Plan Installment Agreements.
