Right. But a couple of people I have talked to thought it did not sound like a whistle. I call it a whistle because that is what it sounded like to me.
So we'll see what happens after I get the gasket in.

but you could also see the leaks on your flanges, and watch the little wing nuts on your studs flap in the exhaust, plus all the soapy bubbles... i mean, what more do you need for me to tell you it's your camsprocketgeardrivespline.

I got the gasket and studs. I took out the exhaust manifold, turbo, and downpipe. I need to adjust the downpipe because it is too close to the stud holes to fit a nut on the studs without hitting the pipe.
Anyway, I took an air compressor and shot air into the turbo. The exhaust side sounded ok to me. On the inlet side I could hear the same sound as before, only it was much quieter.
In fact, it is so quiet I can't hear it in this video. I will take another video with an external mic.

There are 3 areas that I am struggling with in building this car: money, time, and knowledge.
Money is tight and I might get a couple hours of free time a week to work on the car.
I come here looking for knowledge. This is the first car I've ever done more than change the oil on. I've chosen to be a part of this community because of the vast amount of knowledge here and the willingness of the community to share it.
I doubt anyone here will ever be able to assist me with time or money. If you can't assist me with helpful comments and are only going to be rude to me, then please don't bother posting in my threads at all.
Thank you so much to those that have helped me in the last year! I truly appreciate it.
I will put the car back together today with the new turbo/downpipe gasket and see how it sounds.
Thanks again!

You are jacking off about a negligible "problem" that isnt even a problem.
If it is the turbo, the only way you get rid of the sound is by replacong it. That would be STUPID because the turbo might last forever in its current state, assuming there is even a real problem.
A whistling sound is not going to break your damn car. If you really are short on money and time you are likely throwing it at a nonissue.

I put in the gasket between the downpipe and turbo and I got the new studs and nuts and it fits better than ever. There are no air leaks that I could find.
However, the noise is still there. It is not a whistle like I originally thought. I took another video today of shooting air through the turbo. You can definitely hear a ringing noise. And I did discover that the shaft does also move side to side. Not enough to touch the wall, but it does move a little.
You can hear the ringing as it starts to slow down.
I'm guessing the bearings are wearing out and I think I will get a rebuild kit like this - Turbocharger Rebuild Kit - Garrett GT15-GT25/VNT
Unless anyone has any other suggestions.

I think so. I did not find any other leaks.
I don't think the sound is really a whistle or air related.
I believe it might be the bearings, so a repair kit would work, right? If that is the issue....
