Thank you for your reply. I was referring to actual proseries software updates. I found the answer in an old post from 2019. The answer to your question is the IRS will not begin accepting returns until 02/12/2021 and then you will receive acknowledgements. Intuit is holding efiled returns until that date. Thank you.
First, try exiting the program and re-signing in. If that doesn't work, try restarting your computer... if that doesn't do it, try the modem. Exit the program, unplug your source modem, wait 15 seconds and plug it back in. If that doesn't do it, it's a Intuit issue. The entire process will cost you approximately 20- 30 minutes.
Unfortunately, everything is trial and error until you find the source.
