Recycle bin in Lineage OS

[Friek]

Hi,
as my SD card reader is broken at the moment (ticket open, 25 days, no activity…), I have to use the internal storage. I know a TWRP backup is about 4GB large. I hat 2GB storage left and wanted to do a new backup before going over to official Lineage.
I deleted two TWRP backups I had on my phone (they are on my laptop, safe and secure) to have storage. But after deleting these, I still have only 2GB left.
My question: is there a recycle bin I have to delete?
Regards

I had to switch between internal and external memory within TWRP. Then it shows me the correct free disk space.
