In TurboTax Business, check the box for Section B1 (Qualified Business Income Deduction) rather than Box 20. You will need to complete Section A (QBI) of the K-1 worksheet, which may be easier using Forms Mode
TurboTax for Desktop (all versions) has Code Z for Box 20, which triggers follow-up questions to allow Statement A QBI entries.
