Your refund info
The IRS hasn't finalized one or more of your forms. Once forms are finalized, you will be able to access this section.
You cannot file a federal tax return until the forms and schedules that are included with your tax return have been finalized for e-filing. You can see which forms and schedules are not yet finalized by clicking on Review. The section will show you a screen that has the forms and schedules listed along with the date they will be available.
