→ Check entity type before filing

Mailing address variations

Instructions list multiple addresses based on return type

→ Double‑check the correct address

Some think any officer can sign

→ Only an authorized officer or partner may sign

Reason field length

Unclear how much detail is needed

→ Provide a brief, factual statement
