I am using Home & Business desktop for my 2025 return. I have a single member LLC that is disregarded for tax purposes. I cannot e-file my Cailfornia return because Schedule IW lines 3b and 3c return errors that indicate they must be filled. These amounts should be zero because they do not apply, but -0- and "None" are not allowed as values for these lines. If I continue past these flagged fields e-filing returns back to these errors, so I am stuck. If this is not supported in Home & Business then how do you handle single member disregarded LLCs?
