Let’s start over. Why did you get Treasury interest? Did you also get the same interest from a bank like if you cashed in savings bonds? Did you import any 1099 forms? They may have imported wrong. Delete them and enter them again Manually. That usually fixes it. In fact I would delete all the 1099 INT forms, then make sure Schedule B is zero, then add them in and check B after each one.
Interest can come from other places like a K-1 or 1099Div. Look at all the lines in the 1099INT & 1099DIV sections.
