This is a very old post...transferred into this forum last year, but referring to some other year...long ago.
The forms have changed some since it was written, and the later box numbers have changed.

1) TTX doesn't know the amortization period....you must provide the yearly amortization amount yourself....the exact amount for 2019 is either:
....a) shown to you on your 1099-INT form itself (a "covered" bond purchase)
.....b) or bonds purchased long ago ( termed "non-covered"...ie.before somewhere around 2010-2013) you'd have to calculate the amount yourself.
2) depending on the bond type, and referring the current 1099-INT form layout, you would enter show bond interest, and amortization amounts in the following way (but read the main 1099-INT info from your broker's form):
....a) taxable bonds: Interest in box 1, bond premium box 11
....b) US bonds: Interest in box 3, bond premium box 12
....c) tax-exempt bonds: Interest in box 8, bond premium box 13
