look again at the 2021 return, especially Form 4562. 179 is only allowed to the extent you had income before this deduction. any portion that produces or increases the loss becomes a carryover. 179 is a separately stated item on the k-1. was there an amount on your k-1 in box 11? the SDA is not so limited, it can produce or increase a net loss it is included in line 14 on page 1 of the 1120-S. .
