Using TurboTax Business, I prepare Investment Income. When I enter the fields from my 1099-B related to "Short Term with cost basis reported to IRS", and I include "Accrued Market Discount", it seems that TurboTax adds the difference between Proceeds and Basis with the figure for "Accrued Market Discount", essentially counting the "Accrued Market Discount" twice when computing total income. Then, on the 8949 form, column 1f is blank (i.e. no code is provided), even when there is a figure in 1g. To summary, the "Accrued Market Discount" amount seems to be counted twice when determining total income and the "1f" column on the 8949 form is left blank. Both of these seem to be errors in TurboTax.
