Ok after a lot of messing around i got hold of some Italian data. This is not a complete country view, it is only verified municipalities.
There are 21 municipalities in the data set. Total deaths are for 1st March to the 28th March.
2019 recorded 14,603 deaths.
2020 recorded 29,565 deaths.
Change +14,962 deaths.
I have the total Italy country deaths for March 2019 which was 57,882 therefore the 2019 number of 14,603 in the above data represents 25% of the 2019 value.
I would not extrapolate the data across the entire country but i would assume it would be conservative to double that figure and say this has caused at least +30k deaths above normal trendline.
Hopefully my posts with the actual data are.being followed here because it's been a headache to find it.
