way way way too fast.
Also probably too hot.

Even on a good flexibles printer, you'll not get a decent print from a soft tpu at anything much over 10mm/s
Also doesn't hurt to up the extrusion to 110-120%
And make sure your retraction is fairly short. 1.8-2mm.

But primarily, you're printing much too fast. Which is why the rubber has been deposited if fits and starts.

Which brand tpu is it ?

One way to fix this would be to buy some polyflex flexible pla.
Not the cheapest but brilliant stuff for printing with.

But going much slower with a bit more extrusion should also sort it.
