The account number does not go on your tax return. There is no place for it on the tax return. So there is nothing to amend. There is no place to enter the account number in TurboTax because there is no place where TurboTax could put it on your tax return.
If the account number is the only change on the corrected 1099-INT, do not amend your tax return. Don't do anything. Just forget about it.
