Congratulations on the raise! It's always a good idea to re-assess your W-4/withholdings whenever there is a change in income and/or sources of income. Your W-4 with your employer can be updated at any time, and there is no limit to the number of times it is updated.
This calculator is a good tool to use: https://turbotax.intuit.com/tax-tools/calculators/w4/
You will want to have information about all of your sources of income handy when you fill it out.
For the California DE4, there is a worksheet with the form that is useful in determining the appropriate entries: https://edd.ca.gov/siteassets/files/pdf_pub_ctr/de4.pdf
The worksheet begins on page 3 of the PDF linked here.
