I have the same issue, but the numbers do match. We have a single owner photography LLC. There was $279 net income. In form 8960 4a is 279, 4b is -279. 4c is consequently 0. In schedule 1, Part 1 line 3, the $279 appears again as Business Income or Loss. Line 5 is blank (not 0, but empty).
What is particularly confusing is that the error we got back from Turbotax ends with "This issue will be resolved on February 19, 2023. On or after this resolution date you may submit this return for electronic filing."
Does that mean the IRS had a bug???
