On the Form 1099-INT worksheet of Form 1041 the instructions say to enter the gross taxable interest received in Box 1 and the gross tax-exempt interest in Box 8. I could not find any instructions as to where to enter accrued interest purchased on bonds for which interest was received in the tax year.
Same place, but as a negative number to reduce the taxable interest income. Unless ProSeries has a special field for it that will automatically reduce the interest, in which case enter as a positive. Check your output for the correct result.
