Get your taxes done using TurboTax

Same here.  Been using TT for at least 9 years, but now get the same stupid message.  Looking at "active tasks" list, it doesn't seem to be closing, even after rebooting - there are rows and rows of TT tasks active.  Maybe they think you should be on Windows 11?  Customer service has no idea what the problem is - all Intuit wants is your money.
