Stuck on what to do next for this brass..

I'm a natural level 8 blonde, but I've have red hair since November of 23' and last color I dyed my hair was a level 3 burgundy dark brown. I was able to lighten my hair to a level 7/or 8 and I think level 9 at my roots, but my hair is still yellow and brassy after toner, the toner I used was Wella color charm T19. I want to get as much brass out without making my hair fall out! Help! Also if anyone has anything for repairing this bleach damage, LET ME KNOW!

First two pics are right now, 3rd pic was last hair color, and 4th was hair color before that
