I think there is a bug with Schedule C in the section 27b of Energy Efficent Commerical Buildings. Even if you put zero (0.00) it still thinks you have this expense. It forces you to send/mail in the form 7205 although you dont use this expense by default the app may be marking this entry as true.
Please have your programmers review the if else validation statements for this section. If users mark 0.00 for energy its requiring us to mail in the tax return. If TT updates this entry to not require us to mail in the form it should resolve the issue.
Also proabably form 7205 is not yet ready by IRS until 1.29.24
