Is this free to file a federal return, but it won't let me finish without payment.
You didn't say what product you are using, so we have no idea. TurboTax has 2 free products that are free for both Federal and State returns, but we don't know what you are using. It sounds like you are in one of the paid editions. Scroll up in this thread to the answer right above your comment that I left for the threadowner, and it has a detailed explanation of the 2 free products. You may be able to use one of them, if you qualify.
