HI Phoebe - thank you so much for your thoughtful reply!

I am asking about the QBI losses disallowed losses allowed in the current year.  I expected a worksheet but there is not one.  Just one that gives the number, no indication of the calculation, and the numbers seem suspect.  This is in the 2021 program. 

The disappointing thing is that Lacerte cannot tell me how the program is doing the calculation.  I know they usually say  (I'm a 25 year customer) "this is exactly what the IRS says to do and this is how we did it".  But in this case, they cannot even do that.

Thanks for your help.
