The final regulations state "Interest income other than interest income which is properly allocated to trade or business is specifically excluded from qualified items of income, gain, deduction or loss under section 199A(c)(3)(B)(iii)" and yet the S-Corp module seems to default to the position that all interest income is excluded.  I would like to be able to adjust QBI for the interest income that is PROPERLY ALLOCABLE TO TRADE OR BUSINESS. In the S-Corp module, how is this adjustment facilitated.
