State tax filing

This is a little confusing to me. I was also making IRA contributions in those years and live in California. I am retired and taking pension payments. Initially they did not withold anything for state or federal I changed both to have funds withheld for taxes.  So I do have federal and state witholding on my 1099-r. My box 16 is blank. Does this mean I should show box 2b as a subtraction in turbotax when it asks about pension adjustments for my california filing? Or is it more complicated than that?
