Hi Bob Myers,I checked the main list of all Financial Institutions that support Quicken (https://www.quicken.com/support/fi-list-support-quicken-versions) and can confirm that TD Ameritrade Institutional is not listed and does not support Quicken, I apologize.If you would like to ability to track your TD Ameritrade Institutional accounts in Quicken, we recommend reaching out to the Financial Institution directly to request they support downloads to Quicken.Thank you,Sarah
