having trouble change the color of a .png

I may be missing something simple, but I need to change the IG symbol and QR code to white. I am going by the instructions for the color replacement tool, but when I try to click on the black to tell the tool what color that needs replaced, I can't get the other steps to work. This is a graphic that will be a .png that is going to DTF. I am just doing 20 T shirts as a personal promo. Anyway, becasue I am going to DTF, I did't want to get into adjustment layers and upload something that won't print properly.

 

I am on PS 25.3.1. I am also a bit of a novice and not a power user. Maybe I rasterized a layer.......sometimes PS wants to do that? Anyway I am trying to follow the support help (link) and not getting anywhere. I grabbed the IG symbol and my QR code was generated via wix. I imported them as .png into PS. files.https://helpx.adobe.com/photoshop/using/replace-colors.html

Are the pixels already isolated on a layer so you have an alpha channel? The color replacement brush is NOT the answer. You just need to get the pixels on their own layer and then you can simply invert the colors or fill them with white. It's quite a few steps to type out. Is the current png transparent?

The video is more complicated than what you need - just follow my instructions above - it will literally take you about a minute.

    @nelsonmason My first thought, can you just do a 'Inverse' (Command I)... but that would turn it white but the background black. But does the background need to be white or black?

    Actually, the background needs to be an alpha channel Or they are requesting a PNG file. It's funny, but when I hit send on this thing, a bunch of junk popped up in support that said some versions of PS are no longer supporting this function.  

    I don't really know how to do adjustment layers, but I guess I could do it flatten everything and export it as a PNG file and as long as it's white, it's white.
