+Release type: patch
+
+This release fixes an issue when using `Annotated` + `strawberry.lazy` +
+deferred annotations such as:
+
+```python
+from __future__ import annotations
+import strawberry
+from typing import Annotated
+
+
+@strawberry.type
+class Query:
+    a: Annotated["datetime", strawberry.lazy("datetime")]
+
+
+schema = strawberry.Schema(Query)
+```
+
+Before this would only work if `datetime` was not inside quotes. Now it should
+work as expected!
