I think "long COVID" is too vague to really provide a specific incidence rate - it's more meaningful to look at the incidence rates of particular symptoms long after infection. The study I linked finds 27.9% incidence of "confusion/brain fog/trouble focusing attention" and 20.7% incidence of short-term memory loss 8 months after symptomatic COVID infection (confirmed with antibody testing), compared to 14.7% and 5.6% respectively in the control group (who tested negative for COVID antibodies). I don't know or really care if "long COVID" is the right term for what those folks are experiencing, but that result has real practical significance and the rates are way higher than 1%. The same study also finds significant incidence rates for lots of other symptoms that could reasonably fit under the "long COVID" umbrella.
