Trying to send my file to IRS but line 27b prevents it. According to my form a 0 is entered, as it should be. I went back to step by step and have entered everything co?

I've been trying to replay to your post through my Gmail account but apparently that doesn't work. It seems to be so difficult to actually get help through turbo tax 😞 To answer you question I am self employed with two businesses. My carpentry business has a schedule C and line 27b(Energy efficient building deduction) has a 0 on that line. But it will not transmit because it says there is an error that needs fixed. And that by trying to take that deduction I would have to use form 7205, I believe, and mail in my return as Turbo does not support that form 😕😕 I revisited the step by step options and find nothing that I have done to indicate that I wanted to take that deduction?Thank you
