Need a colon on my iphone 11 updated to 17

The colon is above the "M" key on the standard keyboard. On the numeric keyboard, it is to the left of the "!."

On my iPhone 14 Pro the colon is on the 123 keyboard under the 3.

From the standard iPhone keyboard tap the "123" key. The : is in the second row 3rd from the left or under the 3.

If muguy's response didn't help, tell us what language keyboard you're using.
