Carboys, fermenters and kegs; I fill them up all 5 gallons and use the appropriate amount of Star San. I've been watching videos with people just putting a gallon in with the appropriate amount of Star San, closing the lid and swirling around. Am I overdoing it?

I use iodophor, never used star san. But the idea is the same, you don't have to immerse to get effective sanitation. You only need to coat the surface for the required time. Remember, to a bacterium, a drop of solution is an ocean of liquid. I put .5-1 gal. of iodophor solution at 12.5 ppm in a carboy and swirl and shake to keep it all coated for 1 minute, then invert and let it rinse. Done.

I have read on here that Star San apparently works with 20 seconds of contact.

I use a small amount to sanitize carboys or pails.

I have a 25oz spray bottle that I mix a 1/4 tsp of Star San in. Everything I sanitize simply gets a heavy spray. Carboys and kegs get a little extra so there's a couple of ounces at the bottom to swirl around. Honestly, I can get through an entire brew life cycle (from yeast starter to kegging) with a single 25oz spray bottle and still have a couple ounces to spare. I've never had an issue with contamination.

You're doing nothing wrong, nor are the rest of us who use far less and spread it around. You're spending more money that way. But it's all about your process and your preference.

Agreed. IMHO you should do whatever it takes for you to be confident that your equipment is sanitized. If SWMBO brewed she'd probably go through a bottle of Star San every brew day.

Even the foam of StarSan will kill, don`t fear the foam!! HAHA!! Honestly I do as Jerryalan, spray bottle everything and I put 1/4 to 1/2 a gallon in my bucket/carboy and swish it around. I mix up 2 or 3 gallons at a time with distilled water and leave it in a home depot bucket, lasts for months. I even poor it back out of my bucket/carboy to my holding bucket to save some. As long as it isn`t cloudy your good to go.

I doubt it lasts for months. Taste it after a week, it loses its' tartness which means the acid is mostly neutralized. You can verify this with a pH strip test when you first make it and then after it has sat for a week. It will be less acidic and more neutral. So after a week, you will lose effectiveness big time.

I mix up a fermenter load and use that to sanitize everything. I like to siphon it back and forth from fermenters/kegs to make sure I get all of my tubing sanitized. Then I throw it in a better bottle, cap it and save it for another application. I also have a spray bottle which I use to sanitize other things. I don't have the confidence yet to only spray, I feel like a good bath puts my mind at ease.

As pointed out, use pH strips to make sure it is still effective.
