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

[Raspberry]

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?

Yes, the date the asset is placed in service affects the amount of depreciation that is calculated.  The method of depreciation and asset life selected will also affect the amount.  The amounts you listed do sound reasonable.
