State ID

I live in California.  I retired from self employed business in early 2018 and has been on social security since Feb of 2019.  I paid estimated tax for Federal and State in April, Sept and Dec of 2019 because we have few rental properties and some stocks and I know I will need to pay tax.  I am trying to do my 2019 income tax using Turbo tax.  During Federal tax review, it showed an error for me to fix.  On the tax payment worksheet which showed I paid estimate tax for State.  It stated that I need to fill in State ID number if an State payment was entered.  Could you tell me what is the Stat ID please?  I tried my SS number and my State account number which I had when I was working and had my own business but neither worked.  It showed "wrong character or too many character" Could someone tell me what should I put please?  Thank you.
