Retirement tax questions

I encountered the same problem. Line 11 is zero. TT told don't put more than line 11. So Line 12 is supposed to be zero. Why TT still reported error on final review?

 

In my case, I used section 179 in past years for electrical appliance. which no depreciation left. I don't us e 179 again. But CA state created Form 3885A. Can I delete it?

 

Thank you.
