I am not sure I understand why there is a delay.
QBI is not new and is calculated the same as always. Your form site indicates the simplified version is supposed to be available but it does not work in the product. February is very late for those who are trying to prepare returns earlier to confirm expectations. This goes for Business and Personal products.
You already prevent filing when forms are not ready so why don't you implement everything in Turbotax and use 2018 coding/approaches when you are not sure about 2019? That would be a big help to users and I can't see much of a downside for Intuit.
Here's a great example: Section 179 did not work in the Business product until a couple of days ago. Depreciation was set it stone in August of 2019 by the IRS so why the huge delay.
