if you are using a 1099-INT you cannot use the accrued interest box under adjustments to interest unless it is the only type of interest on that 1099. There is a flaw in TurboTax, say on 1 1099-INT, there's $1000 of taxable and $1000 muni, and $200 of accrued interest that relates solely to the muni. TurboTax will prorate this so that taxable and muni will each show up on your return as $900. The workaround is to enter the muni on a separat1099-INT.
