How to move a new layer?

[enginestar]

For some reason I can't post in Gimp 2.10 forum... ? 

I make a new layer. I add an image.
It stays as a 'floating layer' or something.
I can't move it!!
I somehow, after clicking like, mad turn it into a layer.
Sometimes, I can now move it. Other times... I can't!!
What am I doing wrong???

Text layer: I make a new text layer.
Now... I can't move it.
There seems to be some other empty box that gets moved when I use the move tool.

What am I doing wrong?

Thanks.
