Turbo tax seems to think there is one. They have a copy that you can download and print out but nothing that you can efile with.
My understanding is that they only tax you on interest earned and not on income. So you might not have to file a state return.
In any case you should be able to efile only the federal part and ignore the state. turbo tax will allow you to do that even if you had a state tax that you did not want to finish before you filed the federal.
