Weird "gouge" in print

Hey guys. Ive been struggling for a couple days trying to dial in my TPU settings. I thought I finally had, until I printed this model and found this weird line or “gouge” in the same spot on all 3 prints. The quality of the print is great otherwise, this is the only blemish.

Anybody have any idea what this is, or how to fix it?

Any chance it is the Z seam?
