Thank you for the response, I always appreciate your expert advice @itonewbie!  Some of the capital gains for this return are from the sale of real property in another state.  The sale occurred during the period of CA non-residency and isn't CA taxable.  In the PTO Dispositions entry, I tried setting CA gain to -1 in the "State, if different" override and was able to generate 540NR Schedule D, but Schedule CA incorrectly shows a column B subtraction for this gain with this method.  Without setting CA gain to -1, Schedule CA is correct with no amount in column B, but 540NR Schedule D isn't generated.  In both cases, the column E taxable CA amount is correct and tax liability is correctly calculated, but I haven't found a solution to correctly generate all the CA forms.  I experimented with the "Percentage of source income" override for CA in Dispositions without success.  If I have to choose, I think I prefer to generate a correct Schedule CA without 540NR Schedule D, but FTB instructions are to complete Schedule D for part-year residents with capital gains.  This return also has capital gains from a partnership pro-rated for the number of days of CA residency, which I set in percentage of source income for CA in the PTO K-1 entry, but this doesn't generate 540NR Schedule D either, even though all CA taxable amounts in Schedule CA column E are correctly calculated.  If you have more ideas for CA sourcing and how to solve this, please let me know!

Thank you for the info about the update! I'm still getting the critical diagnostic in ProConnect today, but I'll try again tomorrow.  I see the Lacerte announcement for the final form to be released today, and hopefully PTO will be updated also.

Thank you for confirming.  I also looked in Miscellaneous Forms in PTO for a loss accounts form and didn't find anything.  I can create a form with the required loss accounts information and attach it to the return, but if you happen to know of a source of fillable PDFs for this purpose, let me know - thanks!
