Where is the backup location from Titanium Backup on a phone without an SD card?

I am currently using a Samsung S6. Today I backed up all of my data with the app "Titanum Backup". After backing up all of the data, I transferred the folder of Titanium Backup to my Google Drive. Afterwards, I restored my phone. Then I installed Titanium Backup. However, I don't know where I need to import the folder "Titanium Backup" for the app to restore the the data. I saw many YouTube videos, and their restore was in a SD Card. However, the S6 doesn't have an SD card. Can someone please help me?
