Sign WHERE for 2018 amended California return?

[kauai]

Where do I sign my 2018 CA amended return? Schedule X has no signature line.

I saw a similar question answered "sign the 540" (turbotax Windows)

Yes, Form 540 that printed has room for signatures,

But it is the original 540, not showing changed amounts and shows date accepted in 2019.

Thanks for any help!

ps using TurboTax 2019 Mac OS

You will sign the NEW 540 Form that has the changes.
