No, it's not a known bug. What exactly does "goes in circles" mean? What screen are you on when you have the problem? (What is the exact heading or title on the screen?) What do you enter on that screen? What do you click on? What do you see after you click? If "goes in circles" means that it is repeatedly going through the same series of screens, what are the screens that it goes through?
The tag below your question indicates that you are using TurboTax Online Deluxe. Is that true?
