I am having a similar problem. When reviewing my federal return, I was told that I needed to change a zip code, but the zip code is not the problem. The problem is that the state is entered as NY rather than MA. When I go to 2019 donations and try to edit the problem charity, I am only allowed to change the name and not the address. When I tried to reenter it a new donation, I was not asked to enter any address at all.
I went to Its Deductible, but I could not see any way of changing the address there either.
