Did it ever fit? Is this a used bike that you just purchased? Is it a replacement wheel? It’s possible it’s the wrong width axel on the wheel for that frame.

Is the frame Boost 141 (Boost QR)? Some Treks have this hub standard.
If so: check if the hub matches the frame
Otherwise: squeeze the rear triangle until the hub fits.

Qr should close that gap
