My son cashed in Savings Bonds Series I last Jan 2020 that was left to him by his deceased Grandpa. We took them to our bank to cash but did not receive anything to file with his taxes. Who issues the 1099-INT, the bank or IRS? I called the bank and they don't seem to know anything about a 1099 for the savings bonds that they cashed out for us and deposited into my Son's account.
