Moving Quicken from one computer to another-can see on mobile but not on new laptop

I have a fully updated, synced, and backedup Quicken file on my old laptop (Windows). I downloaded Quicken to the new laptop (also Windows), signed in with my old user name/password (I thought), but apparently set up a new account only. I can see my old accounts (there are two) on mobile Quicken, as well as this new account that has no data. I tried uninstalling Quicken on the new computer to start over, but apparently when you reinstall it doesn't really delete the account. I don't need that new account; I need my two old ones. What do I need to do?
