Those instructions enable you to enter when you provided estimated tax payments but they do not seem to lead you to a place where you can specify non-uniform income, dividends and interest, and withholdings. Those items seem to get spread uniformly throughout the year. For Federal taxes you can spread them non-uniformly and I'd guess the income, dividends, and interest come over to the state taxes but you don't enter the state withholding information when you fil out the Federal form.
