Need help finding duplicate Id's

I think i have a relatively easy ask but im going crazy. I have a table where i need to count the duplicate Id's. I create a simple count measure [ ID_Cnt=count(Id) ] then created another measure to identify the dups [ Duplicate_Cnt = if(ID_Cnt > 1), 1 , 0) ]. It just adds up all the Id's as if the condition wasnt even there. I would like to be to have the total number of duplicates associated with the ID and one measure that has the total count of all overall dups. 

 

Any help is appreciated. 

Here is an example of the data and my desired output:

Duplicates = 5

 11/1/2021  11
 91/2/2021  22
 21/3/2021  41
 41/4/2021  71
 71/5/2021  93

    Duplicates = 
var aaa = ADDCOLUMNS(VALUES('Table'[ID]), "count id", CALCULATE(COUNT('Table'[ID])))
return IF(
    HASONEVALUE('Table'[ID]), SUMX(aaa, [count id]),
    SUMX(FILTER(aaa, [count id] > 1), [count id])
)

     

    EDIT - misread the requirements, have changed the calculation. The above is my attempt. I hope it helps!
