UKR

If you only hold 1 or 2 lots of "incorrect name", edit each transaction individually and change the name.
Otherwise ...

After creating a backup of your Quicken data file go into the investment account register.
Click Enter Transactions and select "Corporate Acquisition"
"Company acquired" is the incorrect security name, "Acquiring company" is the correct name.
"New shares issued" is the exact number of shares you hold in the incorrect security name.
