Under 6,000 lb SUV purchased 6/1/2017 for $41,000.  Took $11,560 SDA on 2017 tax return with -0- other depr exp.  Took regular depr in 2018-2021 of $5,700, $3,450, $2,750, $2,750 for a total of $13,300.

We expected to take $2,750 of reg depr again in 2022, but Proseries is limiting depr to $-0- for 2022.

Why?
