@nj_marcy, by any chance is that separate sweep account actually set up in Q as a "Linked Checking Account"? If you do TOOLS, Account List, and then click on EDIT across from the account name it will show an option to "Show cash in a checking account".This is a convenience (but also a fiction) that Q offers. That linked checking account doesn't actually exist. It's simply the cash portion of my Fidelity brokerage account that's been split out so that I can more readily manage it ... since it's my primary checking account. All cash transactions in my Fidelity brokerage account are automatically swept to the Linked account.
