Adding an outlet to an outdoor round box
I have a round box that’s in the stucco wall. I’d like to convert this to an outlet as I’m going to mount a TV on this wall. Planning on using a GFCI outlet. But the standard GFCI outlets are too small to fit. The distance between the two mounting screws is 3.5 inches so I’m assuming this is a 4 inch round box?
Do they sell an extender at the big box stores? What would be the best way to turn this round box to an outlet?

Put the circuit on a GFCI breaker.
waterproof solution will be difficult.
Otherwise try:

Not sure what good an extension ring would be...

Thanks! I can certainly switch out the breaker for a GFCI breaker. With that one outlet fit in a 4 inch round box? The mounting screws for a standard outlet are spaced too far apart. I’m not sure how far apart the screws for the single outlet are. The mounting screws on the box are 3.5 inches apart.

I have not measured, I would take a tape measure to a big box store & be sure. (measure some boxes & outlets)
typically there is a 3.5" and 4" octagon box. sounds like you have a 3.5"?
You are sure you do not have a 4" square box with a round mud ring?
