When state estimated tax payments are input into the program, the program needs to know which state it is for. So just entering $$ with no state ID is a no-no. States are not identified by numbers - it's the postal code.
If whatever you are trying to do requires numbers then that is not a "state ID" field. If so, please tell us exactly what the text says for that "state ID" field so we can find what it is you are referring to.
