Moving floating Toolbar onto the Taskbar

Thank you for screenshot. If you want to integrate TLB with the taskbar, then close the existing TLB (right-click the empty space of toolbar and select "Close"), then right-click the empty space of the taskbar, select "Toolbars" submenu and select "True Launch Bar...". You can hold down CTRL+SHIFT when clicking "True Launch Bar..." menu item, if you want to select the toolbar folder. This will open TLB on the taskbar. Now you can expand the taskbar and move TLB toolbar to the top (drag it by chevron).

Other way (with the standalone TLB): Right-click the empty space of the TLB toolbar and select "Toolbar Properties". Turn on the Options->Full Row and (maybe) set the Default Style to the "Taskbar" on the "Skin" page. You'll get the TLB toolbar at the top of the taskbar, but it will be not a part of the taskbar.
