Also note that hiding an account does not exclude it from Quicken's calculations, reports, etc, it just moves it to the More accounts areas of the Account Bar. If you want to exclude an account, click the gear at the top right corner of the register/transaction list, choose Edit account details, pick the Display options tab, and select Keep this account separate.On this tab you can also choose to "Close" the account, which preserves its transactions but zeros out its balance and disables transaction downloading. I don't think there is an easy way to re-open an account once it has been closed. Search Quicken help for "account hiding options" for more info.
Rodney, you need to find out why it thinks you have securities in that account and take care of that before Quicken will let you close/hide the account.Maybe go to Investing -> Portfolio and see if you can see what security is in the account and then make a zeros transaction (you can just transfer out the shares). You could also try the Report -> Investing -> Portfolio Value and then have it sort by account.You might also scan the securities once you find them in the security detail. Maybe Quicken inadvertently downloaded a new historical price. It happens sometimes for reasons on the gods seem to know.I have a similar problem sometimes with fractional shares with Quicken gets very pissy about me being off .01 share.
In your original post you said you had a securities value of $19k and a cash balance of zero for a total of $19k. If you withdraw $19k, you will have a total of zero but a securities value of $19k still and a cash balance of -$19k. This may meet your needs, but now your cash reporting may look weird and if the prices of the securities change, your account balance will no longer be zero.It would be better IMO to enter a Remove transaction for the exact number of shares you hold of each security in the account.
