I need to update and amend my State taxes withheld in my CA State tax return. Which form and line should change please?

[sdijaz3]

The state of CA franchise board told me I can amend my state taxes withheld that were not reported on the W2, I am not sure where to amend it at. If I edit the W2, is that the right way to do it? It changes my Federal refund too. Or should I only do it on my state side?

You would start the TT amended return process - that tells TT to "freeze" the original amounts so it has the starting $$ - then make your correction. Correct the state withholding amount wherever it was originally entered - if it's the state withholding on a W-2 then edit that W-2 and correct the number and the change will propagate through the Calif amended return normally.

If you itemized deductions on your federal return then that could change your federal taxable income and you should file that amended return as well.
