If you're e-filing, you only need to mail copies of your 8949 along with Form 8453 if:
- You entered a summary for one or more sales categories (instead of each individual sale); AND
- The sales category for one or more summaries is something other than Box A (short-term covered) or Box D (long-term covered); or
- The Box A and/or Box D summary includes adjustments (typically listed in boxes 1f or 1g on your broker statement).
