how do I pass the online review when TT rejects the box 20 information from my K-1?

For IRS Schedule K-1 (1065), at the screen Enter Box 20 info, select code Z Section 199A information.  A value does not have to be entered.

Then click Continue.

At the screen We need some information about your 199A income, click the box to the left of the item to be entered.  An entry box will open.

The preparer of the K-1 and attachments will provide the information to enter.  You may be entering:

• Ordinary business income (loss) from this business,
• W-2 wages for this business, and
• UBIA of qualified property for this business.

Enter these values for the qualified business income deduction to be calculated.
