My machinery asset deprecation is more in the second year than the first?

The asset was a $6,050 machine press for my business. 100% for business use. 

In 2018, the deprecation was $864 (first year)

In 2019, Turbo Tax automatically calculated $1,482 for the second year.


Is this a normal deprecation rate? How is the amount determined?

I purchased it later in the year (Aug 1, 2018). Could that be a factor?
