Some brokerages supply a consolidated 1099-B that reports the Short Sale in the correct manner i.e. as specified in the IRS Instructions.
Some brokerages do not.
After that TurboTax adds its own checks.
The best approach is to use aggregation.
Option trades are covered transactions.
Covered transactions without adjustments do not require Form 8949. No mailing is necessary.
