My phone doesn’t even have on “my iPhone calendar” as a listed option. Only gmail.

Add a Gmail account Calendar and go back to Calendar to see that On My iPhone may populate.

To improve my understanding of the phenomenon, it would be highly beneficial if you could share a full screenshot (Do not crop it). Visual representations carry a greater impact than written descriptions.

Please remember that this is a public forum, so when attaching a screenshot, please avoid including any personal credentials such as IP addresses, card details, email IDs, Apple IDs, IMEI numbers, serial numbers, phone numbers, order IDs, or any identifiable location information if you are sharing a map.

With the limited information that you have provided, It is hard to even guess the problems faced by you.

Please re-post with detail so that someone else can help.
