This is probably the best post. Your brokerage may send you a consolidated 1099-INT. But you will need to split into separate 1099-INT entries in turbotax for each bond.
Create a 1099-INT for each tax-exempt bond. Enter the Tax-Exempt interest in Box 8 and the Bond Premium in Box 13.
For each taxable bond, create a 1099-INT. Enter the interest in box 1 and the Bond Premium in Box 11. Note that taxable bonds don't have to be amortized, but tax-exempt ones do.
