So I spliced with a #4 from overhead to the garage, as the original electrician did from my Main (at the house) to the overhead.
Sixteen gauge wire to feed and outbuilding does not sound correct. #16 would be used in something like a lamp cord.

i think what he's trying to say is that it's a 7 strand wire. each strand is 16 gauge or something along those lines as a 7/16 isn't big enough for number 4 i don't think. coud be wrong though.

Thanks everyone for your assistance. I figured it couldn't be my wiring as I actually did it correct into the box versus the hodgepodge that was there by whomever owned the house before me. Because I wired correctly, I figured the breaker was now doing its job and tripping due to something down the line. I discovered a rocker switch that was wired incorrectly (had the neural and black tied into the rocker switch) that feed a security light. The switch when flipped off acted like an interrupter and triggered the 20 amp breaker. So I wired it (with both blacks going into the switch) and the neutral separate and now it acts like an on/off for the light...which is weird cause that's how it worked before. anyway, everything is working great. I left the side of my garage that I typically plug in power tools/compressor on the 20 amp and split the other two lines that are just for lighting and extra receptacles on to their own 15 Amp breakers.

Edit: Andrew, yeah. The original wiring had 7 strands of 16 gauge wire bundled together.

A #8 stranded wire with 7 strands would closely resemble this.

#16 wire cross-section area = 1.31 mm

#8 wire consists of 7 strands, 1.23mm each

I dare anyone to tell me that they can see the .08mm difference without a micrometer.
