You're comparing the number of deaths this year only to the number last year in the exact same time. What were the numbers in the years before? Comparing it to only one previous year doesn't allow to say that this is significant. With only one year we don't know the variance of this number. If less than 30% of the additional deaths this year were attributed to corona virus and 30% lies within a reasonable variance of this number over the years, then we wouldn't have noticed, or not?

Same for the remaining info: we don't know how many times it happened before (for example in the previous 20 years or so) that the morgues couldn't cope with more people dying from more people dying from pneumonia (for example during a particularly bad influenza season). That the corpses have been transported away by military trucks also doesn't tell us anything from a statistical point of view.
