If you have business income which requires the filing of Form 8995-A, even if the calculated Qualified Business Income Deduction is zero, you must wait until the IRS has approved that form for filing.

Form 8995-A, the form used to calculate the Qualified Business Income Deduction, has not yet been approved for filing by the IRS. The expected date this will be approved by the IRS is 2/5/2020.

The state and federal governments approve the most common forms first and work their way down the list. Please see the links below for updates on form availability.  Once released, Turbo Tax will work quickly to get it working in the program. Form 8995-A is near the bottom of the federal list.
