I have a Cash Management account at Fidelity. I treat it completely as a bank account and use it to pay my credit card balances monthly.
The problem is that when I reconcile my credit card, the "Make Credit Card Payment" box comes up and the Cash Management account is not listed under "Bank Accounts".
I know why this is happening—Quicken is incapable of understanding that an account that could have stocks could also just be being used as a bank account and let it show up in that dropdown list. For that matter, what if I just wanted to pay my credit card from a cash balance in a brokerage account? Why only "banks"?
I also know that I can choose to create a linked bank account and that it would show up, but I do not want to do that because that functionality is broken—when you do that, it auto-accepts transactions into the register, which is a complete mess as the matching logic does not work properly. Until that bug is fixed, I will not take the linked checking account route. (NOTE: This is not my settings causing the autoaccept issue—they are absolutely correct.)
