Deleting the 0 completely did it for me. The return was finished, I did the double check at the end and it wouldn't let me file. On line 74 excess SDI of which I didn't have any excess there was a Actual "0" on that line Which was correct I didn't have any excess SDI but it would not let me file with the "0" on that line so I just Deleted the "0" an it then let me complete and file the return. Took me 6 hours of searching. I finally saw something on this chat that gave me a clue. Hope this helps.
