My T-bill matured in my Schwab account recently and reinvested in another. But the original T-bill amount still remains in the account and is showing a total value double what it should be. I use Quicken Classic for windows with the latest updates, version R55.15. I update Schwab transactions regularly but I continue to have 2 T-bills showing instead of one. I had already entered the maturity date for the original T-Bill. Quicken won't let me delete it because of previous transaction.
How can I correct my books?
