Lesson Learned:
When asked to "Sign Your Return", enter any 5 digits/numbers for your self-select personal identification number (and another for your spouse if married filing jointly). Before continuing to the next screen, print that screen on paper and save it with other paper documents you retain for your taxes. Suggest not saving a digital copy in case someone hacks your computer and finds it.
It sounds like another challenge to get the IRS to provide you your self-select personal identification number after you file. This is because you'll probably only want to use the self-select PIN if there is a problem with the IRS accepting your prior year's AGI when e-filing. My problem also had to do with ID Theft for our last year's return.
