You can confirm this and find contact/office details on the official House website (house.gov) or by entering your address on a district-lookup tool like the one from the California Secretary of State or Congress.gov. Note that district boundaries can shift slightly with redistricting, and the 2024 election cycle may change the representative starting in 2025.
