Does rebooting your computer help at all?  If not, you could try running the repair updates feature.

I've been getting this all day today, on many difference screens. Tried the reboot. Cleared all cache. Went into Task Manager to see if any programs were eating up memory. Redid all updates. Has not happened all season so far until today.

I was trying to use the "What If" feature yesterday and it kept telling me that filing status was not entered.  It was.  Eventually it did computations anyway but I had to close the warning box several times.  

This has also been happening to me on every screen! I shut down the program and rebooted and it is still happening!!!

Just another Monday

Are you on Windows 10 or 11.  Support says it might be a Windows 10 problem because they are not supporting Windows 10 any more.  I am getting it on Win10

You are not alone in experiencing this error and slow processing.    The product worked fine in years past but clearly the programs in 2025 screwed things up.   This is causing delays in getting returns completed quickly and I suspect Intuit - Proseries will be slow to fix it.

Been getting this message for a couple days after I ran updates . I have an admin computer running Win11 and an additional Win10 computer. This message started on my admin (win11 computer). I was hesitant to update my win10 computer but I decided to run the updates. Automatically after the updates my win10 computer also started with this message. I even removed my win10 computer off of my network just in case my win10 computer was somehow affecting my admin Win11 computer but the message still popped up so this is not a Win10/Win11 issue. Definitely a Proseries issue. Technical support was no help. All they did is send me a email with instructions for troubleshooting. I ran all the troubleshooting they listed and nothing was fixed.
