Generally bad things happen in Lacerte when you enter an override. What did you override. You use the phrase "taxable income" for net of farm loss and Social Security. Must be a lot of SS income. 

Get rid of the override and look at the worksheets Lacerte creates. My guess is Lacerte is doing it correctly.  

P.S. This is not support. This a forum supported by other users. You can call Lacerte and they can maybe help you figure this out. OR come back here with more information. We can not see your work.
