Thanks everyone for your suggestions. Unfortunately none of these suggestions worked for me. I had to click on tax tools and then clear and start over. This reset everything and allowed Turbo tax to give me the stimulus question again. This time I entered the correct amount so everything should be good to go.
This is of course really bad design on Turbotax's part. It should be easy to get back to any previous screen. Obviously it's not ok to knowingly submit incorrect information, and the only way to prevent doing this was to clear and start over. That's awful design.
