Enter your 1099-INT for your U.S. Savings Bonds, paying particular attention to #10. TurboTax will exclude the qualified amount of interest and make the entry on the 8815 and Schedule B. Sometimes, it's easier to delete the 1099 and start over than it is to otherwise diagnose a problem.
It's best to do it from the Summary screen. Simply search for 1099-INT and then select the "Jump to" link in the search results to get to the Summary screen. Click on the trash can next to the corresponding 1099.
