Do I need to file Form 1099-B with state tax agencies?

Do brokers need to file a 1099-B for a retirement account?

No. Transactions within tax-advantaged accounts like IRAs and 401(k)s are not reportable on a 1099-B since gains or losses within these accounts are not taxed until distributions are made.
