I wanted to run a CAT6 cable simply from a first floor room to the second floor room directly above it. I drilled through the bottom plate in the wall on the 2nd floor as shown. I first used a 1/2 in bit, but it was not long enough so I bought a 5/16 one that was 1 ft. Unfortunately I messed up with the first hole and had to stop because due to a slight angle it started poking through the dry wall on the other side (just open air into the house entryway). Seems that the 1 ft one was not long enough either surprisingly because there is still not a thru hole. I'm most worried about whether this is now unsafe, but if not, what is the problem here? Do I need an even longer bit?
UPDATE:
I took out the drywall in the room directly below this, and found a large wooden beam spanning that wall, from at least ceiling level to 1ft down. That wall also has a large opening for a folding door. I fear I really shouldn’t have made those holes— maybe that huge beam is there to compensate for the opening, i.e. lack of studs? What do you think? On the bright side, I got the CAT6 cable out through an exterior wall and ran it up the brick and it looks and works quite good!
Purple is where I know for sure there is wood, green star is directly below the drill holes:

First - you have done nothing that will harm your house other than give a few bugs a raceway, but this is the 50th raceway, not the 1st.
Second - you will have to open it up from below to see what is there. You went through bottom plate and subfloor. You probably (almost definitely not) don't need a longer bit.
