Okay, on the 2818 return filed in July 2019, the program took all Sec. 199A partnership losses as an offset to the 199A calculation even though some partnership losses were not deductible due to passive loss rules. Partner is a Ltd partner. When I looked at the 2018 return while doing 2019 I found that the program had changed 2018 to only use the deductible psp losses in 2018 and carried the non-deductible  2018 psp losses forward to use in 2019 to the extend they are deductible ln 2019.
