TWRP help OnePlus6


Hello. I have recently rooted my OnePlus 6 using this video I did the part where you install TWRP permanently and then I rooted. The root disabled my internet, so I unrooted my phone. I don’t have root anymore, but I’m not sure if I have TWRP. When I reboot into recovery mode, I am not sent to the TWRP screen ever. Do I have TWRP? If no, is it safe to lock my bootloader. If I do, how can I remove it? Do I need to provide more info?
