Can I edit the county I live in from what Turbo Tax listed?

Yes, you can.  It won't be in the My Info portion of the return (that is, the information that populates the federal portion of your return), but in the state part of your return.

To change your county of residence in TurboTax Online: 

1. Open TurboTax Online
2. Select  Tax Home in the left pane
3. On the  Hi, let's keep working on your taxes! screen, select the dropdown on the right side of the State Taxes box, then select Start, Continue, or Review/Edit
4. Proceed through the state screens until you come to the Status of your state returns screen
5. Select  Edit or Continue to the right of your state
6. When you come to the Your 2023 [state] taxes are ready for us to check screen, select Go over [state] again
7. Within a couple of screens, you'll come to a page that lets you enter/edit your county
