Hi, Ira.
As JM said, we need a lot more information before we can give an intelligent answer.
First, the Internal Revenue Code taxes gains on "sales and exchanges". In other words, an exchange of properties is just as taxable as a sale. Gain or loss is measured by subtracting your adjusted basis for the property traded away from the fair market value of the property received. Fair market value for the two properties is deemed to be equal and set at whichever can be more easily and accurately determined.
Second, there are many exceptions to the general rule. These exceptions are all spelled out in code sections written by Congress to accomplish certain governmental goals. Many corporate transactions are very carefully structured by management (with advice from attorneys and CPAs) to fit within one of these exceptions. In order for us to know how a particular transaction is to be treated for tax purposes, we need to read the voluminous documents from corporate management to see which code section applies.
Was your mutual fund exchange engineered by the fund managers to fit a code section? (This is not too unusual when managers are re-aligning funds within the "family".) Or was it a straightforward exchange that you initiated by calling your broker and saying that you think XYZ looks better than your ABC, so please swap them for me? (In that case, you would treat it as a sale of your ABC and a purchase of XYZ. All prior basis numbers and dates would be forgotten after the ABC sale is recorded.) Or did the exchange happen in some other way?
If this is an management-initiated exchange, you should have received information about what happened "in the real world". With that, you should be able to figure out how to record it in Quicken - and we'll be glad to help. You also should discuss this with your own CPA and broker.
