I struggle with this problem every year, and it always comes back to me forgetting to put a check in both the ordinary business income and, in my case, the UBIA boxes. They want to sell you a more expensive program, which I don't need, so not all information will transfer over to the 199 sheet. If you don't re-enter the OBI here again, along with the UBIA information that it really needs, when the program asks "We need some information about your 199A income or loss," it gives you the error and won't let you file. I make this same mistake every year, so I hope this helps someone. Good luck to you all.
