Do I need to amend CA return for a code G 1099-R with no tax implications?

I forgot to attach 1099-R form with my returns (it was a code G traditional to traditional rollover), so no tax implications. I was able to amend my federal tax returns online but for my California returns turbo tax says I will need to print my amended returns and mail it in. I wanted to know if this is a mandatory step (or can I skip amending my CA taxes) as there are no tax consequences of this change.
