2019 returns will not save to .pdf

To answer your question, yes the software is updated via the internet every time I open the application. I am using the application locally which I originally installed from a CD. Again, I am on a Mac using Mojave and I have been using TurboTax since 2007. My normal workflow is to review and proof the return as a .pdf prior to filling them. (After filing, I create another final .pdf for my records and discard the proofing copy. If necessary I will print a few pages from the .pdf.) As stated originally, the application "hangs" when attempting to create a .pdf for proofing.

Since I do a couple of tax returns for others in my family, I took a chance with the TurboTax application and filed a federal and state return for the person with the most simple returns without having reviewed and proofed them as a .pdf prior to filing.

To my surprise, after filing the returns, I was able to create a .pdf of the returns anywhere in TurboTax where the option exists to either print or create a .pdf. And, of course, I was able to print from the local .pdf document. This behavior must be either a bug or by design in TurboTax 2019 where printing/creating a .pdf can only be accomplished AFTER filing a return. Please advise. If it's by design, the application should explain why instead of just hanging! Unfortunately, now I must review returns prior to filing from the "forms" section of the application which does not present the returns in the same format as the actual returns.
