As of today (3/18) the problem persists.
Problem Summary:
When printing on MacOS, you get the pop-up message:
"Please wait while we prepare your tax forms for printing. This initial setup process may take 2-3 minutes. Thank you for your patience"
After about 5-7 seconds, the above pop-up message disappears and nothing happens.
Temporary Solution:
One can still save a PDF copy of the return by going to the Turbo Tax system menu:
TurboTax ---> File--> Save to PDF ---> FileName/FolderName
