Odd object just North of Tonto Basin, AZ

I was taking a picture of the cloud formations over my town, and when I got home and examined the photo at near-pixel level, I noticed this strange object.
At extreme close-up in my paint program, I just couldn't make out what it was. Just looking close-up at the nearby cloud it's under.. it didn't quite look like a jet - this area does get a lot of ground-based aircraft fly-overs. As such, I cannot verify what this object is using just basic home-computer software. I'm hoping someone(s) can better clarify its image. Since to me it doesn't look like a jet, etc. I wanted to submit this photo I took with my Samsung A21 phone's camera. It doesn't appear to me to be bad pixels, but I'm not sure.. From the distance I was from the object, I didn't notice it until I zoomed in on the photo. I didn't enhance the photo in any way.. and just placed a yellow box around the suspected object to help you know where to find it. It is in JPG format, which I downloaded to my PC.
