I'm having some difficulty picturing what you mean by "It is filled in, but it isn't using it, but it is using the Category from the Memorized Payee List. "
Do you mean that the information in the Memo field for the Memorized Payee is not being entered into the transaction Memo field and instead the Category for the Memorized Payee is being entered in the transaction Memo field?
If so, there are a few things you might want to look into/try:
Let me know if this answers your question. Or let me know if you are talking about something else and we can take it from there.
Are you relying on Quicken to create new register transactions from downloaded transactions?
There also is a (relatively new) option available for each account register in Edit Account Details, Online Services tab: "Don't update memo when downloading" Is that option turned on or off for this account?
It's my understanding that you must have created a register transaction with Memo text before downloading from the bank if you need to retain a certain Memo text in the register. When matching download to an existing register transaction, Memo remains as entered. If Memo is blank, Downloaded Memo replaces Memo. And then the program code changed to accommodate the new option setting and I don't know what that will do now … a programmer would have to review and comment on this.
Since I'm always creating my register transactions manually or by scheduled reminder, transaction downloading only serves to spot-check my handiwork. I don't rely on Quicken to do my work for me … that's like relying on the Autopilot in driving your car while you nap. It might be best if you recorded register transactions first, then let Quicken match downloaded data to your already existing register transaction without replacing Memo with Downloaded Memo text (or blank).
