Oakmark changed my mutual fund class from Investor (OAKMX) to Advisor (OAYMX) on 1-26-21, and unfortunately I erred when trying to incorporate that information into Quicken (Quicken 11). To make the current share balance coincide with the balance after the change I simply added a partial share based on Oakmark’s numbers, which then resulted in a very small error in the amount of shares in each transaction prior to 1-26-21. I should have known better. Apparently (per Quicken Help) I should have used Corporate Acquisition under Enter Transaction. I have now deleted the five transactions post 1-26-21, as well as my small Add Shares transaction on 1-26-21, in hopes of establishing the correct information for all the pre 1-26-21 share transaction amounts. The current symbol for this fund showing in Quicken (edited via Edit Security Details) is OAYMX—I must have changed it at some point. And that brings me to my question—I have encountered a dialog box regarding Symbol Change (see attached image) and I do not know how to proceed. The dialog box comes up when trying to edit the symbol name. I clicked on OK in the dialog box and I am not sure what occurred—the erroneous share transaction amounts appear to be unchanged. It may be that there is no easy fix for my error, but advice on how to respond to this dialog box would be greatly appreciated.
