    If the device can't be seen you probably haven't got USB/ADB drivers installed on your PC. https://www.getdroidtips.com/downloa...s-usb-drivers/

    You can't run TWRP from adb, it's in the recovery partition, not the Android partition.

    If the phone doesn't have an SD card slot, you'll just have to clear up some internal storage. (If it does, back up to the SD card.) Remember, only back up data, and don't run Tipatch unless you have loads of backup space. (If you did, reinstall TWRP and don't apply Tipatch.)

    If you want backups of anything else (system doesn't need a backup, you can download it from the Lineage site), back up your data, copy the backup folder to the PC, delete it on the phone, back up EFS, or whatever else you're backing up, copy that to the PC, delete it from the phone, etc. (If you're backing up more than data, create a folder in your Backup folder [on the PC] named with the date of the backup. Then put all the backups, the sdcard contents, anything else you're backing up, in that dated folder. I do that any month I'm backing up anything new - and with a Pixel, that's an update, so a backup, every month. I'll be doing one this Monday or Tuesday. And I still have at least the TWRP data backup going back to the one I made before I set the phone up. [2TB data drive n the PC, so plenty of room to keep backups.])
