The Targa file format doesn't store transparency in the same way as formats such as png so it needs to have an alpha channel which is a component of an image which describes how transparent each pixel is... > https://graphicdesign.stackexchange.com/...targa-file (yeah that's not from me, just clicking on google first link)

Here also is a good read about targa > https://community.adobe.com/t5/photoshop...-p/3588469

Roughly, your mask needs to be an alpha channel, thus copy your mask and paste it on the alpha channel or create a new one called "Transparency" and copy your mask on it, as it is said in that post in the last link.

On GIMP it would be something like:  In the layer's dialog CtrL+Alt+Click on the mask to make it visible on the canvas, then in the Channel tab/dialog drag down any channel, then go back to the layer's stack and do a Ctrl+Alt+Click on the mask to remove its visibility as a "working layer" (Ctrl+Alt+Click on the mask is a toggle)... roughly.. (maybe you need to delete your mask after that, I did not try)

When I add the transparency image it goes onto the image as a new layer like this. When I ctrl alt click on it nothing comes up so I can't get through this part. I don't know why it makes a new layer above my own image.

Click on that button to anchor it (Before "Paste" ot "Ctrl+V" you have selected the mask...)
