Rick be right, I bet.

Lacerte provides 'general info' that shows the carry-over & I think it is also shown on the f 4562 (top section).

So you're likely better off with bonus, assuming the shareholder can use the loss on the F 1040 (assuming basis limitations aren't a problem..)

AND, Lacerte makes it hard to keep the balance sheet balanced - I have to override in M-1  IF you have suspended § 179.  (P I T A)
