It seems like you may have found your answer, but here are some helpful resources for entering 199a information into Lacerte:
Lacerte QBI - Simplified Worksheet
@JLaub income entered on Lacerte screen 14.1 flows to line 21 Other Income, which would not rise to the level of a pass-thru entity, and therefore not included in the QBI deduction calculation. If you want the income to be included, you will need to include it on a pass-thru like schedule C or F.
Ok. Thanks for the reply. But, can you give me one instance where income input onto the Misc Income line S/T S/E tax would NOT be available for the QBI deduction? I would think it would be automatic.
