Solved
It only will let me change the zip (which is already correct) the state is what's wrong. Also, it's not wrong on the 1099-int, just in TurboTax.
I found the solution myself, it's to delete the 1099-int and manually enter the data. Frustrating that I can see people have been having this same problem for several years and TurboTax hasn't fixed it.
