Without a complete question, one can only guess at an answer, I
suppose. It's impossible to say whether the original question was
about the grammaticality of
We don't have uploaded (something) or about the grammaticality of
We don't have (something) uploaded. Given that the full and consecutive set of words
We don't have uploaded was given with nothing intervening between
have and
uploaded, I concluded that I should answer as if the question concerned
We don't have uploaded (something).
