Lacerte does a great job with any of the routine Fed vs CA differences & non-conformity (the adjustments are on shown on F.540-CA).

And I'd be surprised if there isn't won't be a built-in way to deal with the PPP non-deductible expenses issue.  I'm too bogged down with year-end payroll issues to have even looked yet.  At a minimum, there's a place to add the PPP amount back as income which gets to the same taxable income.  At the Spidell webinar I took back in December, the instructors weren't sure what/how CA wanted it to be presented.

Fortunately "we" have some time to figure it out ... maybe the 2.12.21 delay is a good thing?
