Anecdotally, living in London where we have congestion charge, I doubt it changed GDP much. GDP is basically total spend and if people don't spend on one thing they'll probably spend on another.
In terms of real economic output I'd guess it helped a bit as it made things quicker for workmen who needed to get around while reducing the more leisure driving. But we've had lots of much larger changes like covid and brexit that would probably drown things out in the numbers.
