Filing

I am getting the same error message over and over again and although sure I did not accidentally put my spouse's in my space I did press back to double check and as I expected I had not entered his information. I have filled in the page about 8 different times now and can also assure you I am not now entering my sin on that line so they match. I am entering his sin which is different from my own. How do I make the error go away now. I can also assure you I am entering it correctly 9 digits no spaces when I finish and move on the spaces are added for me. I've also tried adding the spaces myself but it doesn't appear to matter how I type it, the program thinks they match.
