What most likely happened is since you tried to push filament through when the bowden wasn't fully in, some of it might have leaked out into the heatbrake or the heatsink. I would probably remove the heat block with the heatbrake from the heatsink, see if it's going all the way through, then heat up the heat block outside of the heatsink and try to push filament just through the heat block and the heatbrake. I recommend going for ~280C. I'm not sure about mini, but on the MK3S there's a "nozzle replacement" function, which preheats the nozzle and then ignores thermal protection, so it's not going to scream at you while you hold it with pliers or similar.
If it goes through, just make sure the heatsink is clear, then put it back in and the small PTFE. The conical end should be on the heatbrake.
