When bond matures how should you categorize transaction downloaded from broker

Here's what I do by way of example. I purchased a $1000 T-bill for the discount price of 975. When the bond matures, I delete the downloaded transaction 'redemption' from my broker to avoid the improper realized gain and income issue you're having. Instead, I use the Return of Capital transaction to return my original 975 investment. I then enter a new interest transaction for $25, to capture the investment interest income properly in my investment income report. There is no capital gain realized upon maturity—only a return of principal invested at par value. I then remove the T-bill 10 shares (10 x 100 =1000) shares from my register using the Remove shares transaction. So in summary--- I buy the bond at a discount to par value; it matures at par value and I get my original investment back plus interest (difference between par and discount price). The bond no longer exists so I remove the originally recorded shares from the account. The interest earned from the bond is properly captured in my quicken investment income report.
