You are probably thinking of the reports last year of phosphine in the upper atmosphere where the quantity turned out to be overstated by a significant amount.

On the other hand, there is a sweet spot in the Venusian atmosphere where the temperature is low enough and the atmosphere provides enough protection from solar radiation that microbial life could conceivably survive (which is not the same as saying there is any life there); there are certainly plenty of Earth microbes that live in environments just as inhospitable if not more.
