What kind of downloads? And disappeared from where--your computer or your online account? Are you referring to desktop software downloads in your account? If you're not finding some software download purchases in your account, you likely have multiple accounts we can help you troubleshoot.

This is mainly a user community forum--not a direct route to TurboTax Support. But we may be able to offer some suggestions.
What is it you are wanting to do? Are you referring to the TurboTax launch icon? If your icon disappeared, does that mean you are wanting to create a new shortcut icon on your desktop screen to launch TurboTax from? Are you using Windows or Mac?
What do you mean by your "sidebar"? Does that mean your Windows Start Menu?
In the Windows version of Home and Business, this is the Path to the executable to launch TurboTax:
C:\Program Files (x86)\TurboTax\Home & Business 2019\32bit\TurboTax.exe
Do you see the program executable file in that location? If so, you should be able to make a desktop shortcut to that file.
