3 days back I have created a report in my org and after some times I deleted that record ..even i deleted report from recycle bin as well

Now it's been 3 days still that report present in salesforce database

when query with all rows in execute anonymous, soql returning report details

check the created date and it is deleted but still this is in memory..

A way tried by myself. I created 25 K Account records and deleted those records, also deleted from recycle bin

I thought hope this may delete my reports from salesforce database but no :( this report is still in memory..

Looks like I need to wait till 15 days to remove from back end database.

because of this I am unable to create another report with same unique name.

I know if I change the report name it will work but in my case I need to create report with same unique name because of lightning badge :(
