glitch in business property sale

Lost now, forms due in 2.75 hours. 

I have a 45k loss for "business property sale." 

Did not enter one; don't have any. Had a casualty loss, but can't "see" the form and what I did wrong. 

It is not the 4797. How can I look at the forms on my return to find it? How can I fix it?

 

It's taken me two days to get to nearly finished, and I don't have time to erase and start over.
