@JM136 - unless you step foot in California, none of your income is 'California sourced'. You would only pay tax to Ohio as that is where you work and reside.
"California sourced" refers to whether you generate the income while in CA, not that the organization who you perform the work for is located in CA. Otherwise every Disney employee working in Florida would have to pay tax to CA as that is where Disney is located.
good article here:
https://moskowitzllp.com/what-is-california-source-income/#:~:text=If%20you%20are%20a%20nonresident,....
from the article:
"If you are a nonresident with a business, trade, or profession that conducts business both within and outside California, the income generated from business you conduct within California is California source-income and is taxable in the state.
Since you are not setting foot in CA, you do not owe tax to CA. if you go travel to the client for let's say a week, then yes, that is CA sourced income and taxable to CA (but you'll get a credit from OH so you are not taxed twice on the same dollar of income)
