Business & farm

Looking back on my 2018 return, I see, for example, that I specified "carpet replacement" as a Section 179 item of about $2300, but it looks like it was not included in expenses for that property.  It certainly wasn't flagged in the Federal Review, so I guess it was a program error.  Groan!  I really don't want to go back and re-file.
For this year, I went back and changed the Section 179 entries to Special Depreciation Allowance. as you suggested, but it still didn't change the bottom line.
