The SE Health insurance deduction will not be taken on the individual side in Lacerte. 

The reason this deduction is not taken on the individual level is due to the fact that the SE Health Insurance Premiums should have been included in the wages amount reported for the Partnership or in the Guaranteed Payments so it is assumed it is already accounted for in the QBI calculation. 

If it was not reported already elsewhere on the K-1 you may need to override the Qualified Business Income on the K-1 Line 20 in the Qualified Business income [O] field.
