Welcome to the forum!
Yes, that is way overstocked. The fact that it's a corner doesn't give it a lot of length. Besides, you want to put 34 fish in a 20 gallon tank. I overstock my tanks, following the 1 fish per gallon rule. You would be pushing 2 fish per gallon.......
IMO tetras are pretty boring, and are good filler fish. I have a 30 gallon tetra tank (neons, black neons, orange flames). The stock is 12, 6, 8 and there are also 7 or 8 kuhli loaches. While the colors are pretty, that's really all the tank has going for it. I would mix it up and keep a couple schools of different types of fish, rather than do 3 different tetras.
