It does not go on Sch C or E, but that would give it the same tax rate treatment as on a correct Form 4797. Per the Form 4797 instructions, the sale of business property which was deducted under the de minimis safe harbor goes on Form 4797 Part II Line 10. I know what the forms should look like if prepared properly, I just wasn't able to figure out how to get TT to do it correctly. I did eventually find a solution thru the TT Sale of Business Property by clicking held one year or less, entering the actual purchase and sale dates (which are long-term), and TT reports it correctly on Form 4797 Part II Line 10 (ordinary income) and taking it to Form 1040 Schedule 1 Part 1 Line 4 which is correct.
