Many to one relationship not recognised as list

The accounts object is not recognised as a list, when it is a many to one relationship. Am I doing something wrong here?

```

if TYPE_CHECKING:
from .account import Account # noqa: F401

class User(Base):
id = Column(Integer, primary_key=True, index=True)
accounts = relationship("Account", cascade="all,delete", backref="user")
```
