mnelson8215,
You are not alone! I have had to go through this hassle just about every year. You will need to clarify a couple of things so I can intelligently advise you.
Just to be sure ... does your TD Ameritrade 1099 statement show you received exempt-income dividends? That would be a nonzero entry on line 12 in the 1099-DIV section. If so:
(1) Are you holding mutual funds and/or exchange-traded funds (ETFs) in your TD Ameritrade account?
(2) Are you holding municipal and/or state-specific bonds in your account?
(3) In the later section entitled Detail for Dividends and Distributions, do any of the securities show a non-blank entry under the column heading State?
If the answer to (1) is Yes, provide the name of one such holding, or at least the parent company, e.g. Fidelity Investments. Ditto for (2). I ask these questions because in most cases, you will need to go to the various parent company's individual website to find the answers.
