How can I opt out the QBI deduction?

It's an automatic calculation, there really is no way to not take it if the credit applies.

why do you want to opt-out?  there is a way if it's from dividends leave line 5 from the 1099 blank

for businesses, you would have to check the box that they don't qualify for QBI.

I could understand if you had a small 199A dividend and would rather forgo the deduction rather than upgrading Turbotax.  For a business, I'm not sure this would be advisable if it does qualify.
