I eventually solved this (really only cosmetic) issue with a simple workaround. In the imported 1099-OID forms, the only non-zero entries were in box 6 (Acquisition premium) and box 11 (Tax-exempt OID). I changed the boxes with 0.00 entries to blank in each of these forms. This eliminated the spurious "0.00" entries for these forms in Schedule B. It would be nice if Turbo Tax could recognize that the original imported forms resulted in no taxable interest, and did not generate Schedule B entries of 0.00.
