What IRS address do I mail in the more detailed breakdown of 1099-B to and do I also need to send to state?

I'm inputting in a summary P&L amount from multiple trades from an institution that does not send 1099Bs to the IRS. This will require me to mail a more detailed 8949 csv of my trades. What is the address I need to mail this information to? And also, if in CA do you need to mail it to the state?
