How to correct the error: line 27 b section II of schedule C: there is a zero by default and can't be changed.

Schedule C line 27b requires Form 7205, which TurboTax does not support. There is no way to claim the energy efficient commercial buildings deduction in TurboTax Online.

don't know about online but in desktop the version the last line in the expenses section is for the 7205 amount which you must compute using the form.  this will require you to mail in your entire return because there is no way to submit the 7205 separately or electronically.
