The only H.E.B. store around here that I can think of is Central Market. I
was there last week for some Guinness, but I didn't see the tortillas.
Okay, so maybe I was distracted....

Those aren't zero carb.  (God, did I just channel JCDK for a second?)

65 total calories, minus the 12 calories from 3g of protein, minus the 9
calories (from 1g of fat) leaves 44 calories coming from carbs (because
there's no place else for calories to come from).  44 calories means 11g of
carbs, so the fiber has already been subtracted from that "11g" carb count.

I think there must not be a strict requirement in the US that manufacturers
do this one way or the other consistently - I see some food labels where the
fiber grams aren't subtracted from the carb count, and some where they are.
(Not surprisingly, most of the products where it's subtracted are
"reduced-carb" products.  They're probably hoping that people have just
adopted the simple "subtract fiber grams from carb grams" rule, and thus
their products look lower-carb than they are, without the manufacturers
having to actually come out and lie or anything.)

I've heard, but not looked closely enough to know, that on EU labels, carb
counts always mean "net carbs", and fiber counts always mean
indigestible/non-caloric fiber.  That makes sense to me - but until the US
goes consistently one way or the other, shopping will involve math.  (I
don't mind doing math, but I do wish labels were more useful)
