getting dyed red to blonde help

So I've asked around many different places in my city and get different answers from everyone, so I'm turning to the internet. I've been dyeing my a hair box dye 7R red for about a year now, and want to go blonde. I messed up and had a friend dye it dark vivid red, and it just wasn't what I wanted so I used color oops to get rid of that dye job. It actually turned to this nice yellowy shade but it was still too dark to be blonde. I waited a week then did a bleach bath, but it only turned my roots yellow. Now my hair is this strange glowing orange/yellow. I just want a nice golden blonde.
My question is how can I get there? Do I need to use another color remover to minimize the red, or bleach again? I think my hair is too dark to use toner, but I'm also super new to this and don't quite know what's even going on.  :laugh:
Thanks for the help!!  😀
