Allow me to provide some more information about integration with Quicken and QuickBooks.
QuickBooks is a more advanced version of Quickens that offers payroll, inventory tracking, 1099 tracking, and accountant access. Due to all these extra features, the option to convert a file from Online to Quickens isn't available. However, you can convert your data into a .QIF, .QXF, and .TAX file and upload it to Quickens that way. The Quicken support page on importing data will provide more helpful information.
I'm only a post away if you have any other questions. Best wishes!
