Trouble with BLTouch and homing

So a few years ago I built a prusa clone back when everyone was using ramps1.4 and arduino ide to compile firmware. Things ran fine for years and then I sorta took a break from everything 3d printing. Now im getting back into it again and decided it was time for an upgrade but the 3d printer tech moves quickly and i was quickly left in the dust. I was very lost in VSCode and platform IO, it may be easier now but it just was NOT what i was used too and not to mention I was always very inexperienced with the coding and firmware portion of building a printer and that seems to be where my issues are now. I decided to upgrade my mainboard to an SKR1.4 Turbo along with Tmc2009's using UART, a BLtouch and a Titan Aero i had pruchased a while back but didnt get around to installing. I was also using mechanical endstops before and i have since switched over to using the TMC2009's for the X and Y endstops instead of mechanical. Now my problem seems to be regarding the bltouch. It seems to be working correctly as far as I can tell, I can get it to deploy and retract along with the self test. But the issue is when i go to home Z moves up away from the bed and then tries to probe(z moves in correct direction if i move it manually through the screen. I have my z offset set to -2 and have also tried -8. I could be doing something completely wrong but I just don't know. Anyone with a solution please help lol, I have been bashing my head against the walll for about a week now and I feel like im trying every possible wrong thing in hopes of eventually coming to the right answer... My config files are attached and please don't be too hard on me, I can build just about anything as well as take apart and put anything back together but ask me to write a simple hello word script and i cant do it lol... please help before i mess something up even more lol... i just want to get back to printing with 2 printers and then back to building my core xy.. Please any help would be greatly appreciated the printer loooks soo good now and like it would be a beast of a printer if I could only get the firmware or z offsets sorted out! I'm assuming thats what my issue is but really im just guessing!!!

Github to my Config and Config.adv

here is a github to my config and config.adv. I'm sure someone out there is running a similar setup and can help me out. its basically a prusa clone. I basically copied Tom's prusa clone build and have changed a few things but basically the same thing. Please help!

in your Configuration.h you have "Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN"

Is the black and white cable in the z endstop plug or is it in the dedicated probe plug?
If the latter do not enable Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN

Yes it's in the dedicated spot. But I may have just recently uncommented that out in desperation lol. I will try in the morning and post my results! thank you so much for looking through my configs! I've also thought about starting over from scratch and or taking a generic config that someone has online that's close and then I could just edit all of my values. I will def try to uncomment that tomorrow and go from there. I feel like i'm close but something just isn't quite right!

the black and white cable also has polarity. It must be plugged in the correct way.




The black wire needs to be on the gnd pin.
