Enter the 1099-INT at the the interest income section. TurboTax (TT) will detect that it is savings bond interest and ask about education expenses.
At the screen "Tell us if any of these uncommon situations apply"", do NOT check the box "I need to adjust the taxable amount". Click yes when asked if you used your bonds to pay for higher education expenses (the fine print tells your QTP counts). At the "Report educational expenses and benefits" screen, enter the amount of the QTP contribution as "Qualified higher educational expenses paid in 2019". At the "Additional Bond Information" screen, you enter the cashed bond info.
