It’s a hidden folder inside of your Insync folder

How to retrieve lost or deleted files

Check Google Drive web (drive.google.com) trash to see if the deleted files are there. If not, go to the .insync-trash folder. It is a temporary hidden folder within your Insync folder. Files are temporarily kept in the .insync-trash folder for 30 days before being deleted.
