State tax filing

What do I do if I already filed and send a non-signed 8453-LLC? The statement on the Intuit TUrboTax Electronic Filing Instructions say to "Sign and date within 1 day of acceptance." Does this mean that once I receive the email that the California return has been accepted, I can e-file? How do I e-file or where do I attached/upload to?

 

Also, since I already filed it with Federal and state with 8453-LLC NOT signed, do I need to amend and sign/attached?
