Vitamin D level of 19.3 ng/mL is indeed insufficient — anything below 20 is considered deficient. Uprise D3 60,000 IU once weekly for 6–8 weeks is a standard correction regimen and appropriate.

Stick with Uprise D3 as prescribed, unless a specialist later advises adding K2 based on specific needs.
