I saw you asking on my video on how I do mine. I dunno when I'll be able to do a video tutorial any time soon, but I can help explain it?
First I blur the background:
Take the LASSO tool and draw around yourself, then once that's all selected and highlighted, go to "effects" and then "blurs", then pic gaussian blur.
Background blurred, check!
Next I make rectangular shapes for the title.
Go to the shape maker tool, pic the color that you want and then draw them in! You can adjust the opacity on the layers toolbar.
Then add in some font and whatever else.
A lot of photoshop is just trial and error and figuring things out
