Do you have any advice on editing the address of my childcare locations? I am trying to complete my California return, and the existing address is incorrect.

Information flows from the federal into the state forms so the corrections have to take place in the federal form if this is pulling from the federal section for Dependent Care. 

In the federal, go to Deductions and Credits
Scroll down to You and Your Family and click on Show More
Click on Revisit for Dependent Care Credit and you should be able to change the address there
