Welcome to community.
Actually, you can find those issues via JQL.
Let's say, original estimate is 8h and you logged work 6h. So you used %75 of the estimation.
Go to "Issues -> Search for Issues" and run the following query, it will return the issue above.
To find issues where you worked more than %75
Or use this one to find where you work more than estimated
You can also create a filter and subscribe for e-mails notifications.
Hope it helps.
