This worked for me:

"If the error persists, Right-click on the file and select rename. Change the file name slightly. Restore the client file."

I did it a little different from another Intuit post: I copied the file to another spot on the PC. The info suggested Desktop.

I right-clicked and changed the name to Smit1234_fixed.24i. Then copied it back to the data directory.

Home Base Maintenance in the menu brought the new FIXED file back to PS Home Base. YOU DO have to remove the original one otherwise there will be two files with the same SSN trying to e-file.
