Ok, Ive got clients with a similar situation in 2020, (husband sole earner, self employed, wife didnt work at all) they each put 6000 into IRAs, but Im not seeing any adjustment for the IRA on the California CA....

Line 19 of the California CA is the IRA contributions (and I dont see any column for making adjustments to the IRA line, theyre greyed out), Line 23 is the total of adjustments from the lines above....are you sure its the spouses IRA thats being adjusted?
