I'm not sure I fully understand your question but I will try to help.
Income reported to you on 1099-G is entered into Turbotax (TT) in the Personal Income section, Other Common Income, either for tax refunds or other. Just copy the information from the form.
If you have information on your W-2
box 17 (state income tax) include that when you add your W-2 information into TT under the Wages and Salary section of income.
If you receive a 1099 B that information is also entered into the TT income section. Depending on the details, that will be split between into the various sections of Investment income. Most brokerages also combine interest and dividends onto the same form, which goes into the Interest and Dividends section. Usually, taxes are not withheld, if they are just copy the information when you fill out the sections. As a suggestion, most major brokerages will let you download the 1099 directly into TT which will automatically populate the appropriate fields.
