I started a small business in Florida, should I keep filing for Form DR-15, "Sales and Use Tax Return", every 3 months or file Form DR-405 from TurboTax?

My son has started a small business in Florida in 2018 and the Florida Department of Revenue told him to file Form DR-15, "Sales and Use Tax Return". He's been filing Form DR-15 every 3 months. However, when I downloaded TurboTax for Florida, it ask to file Form DR-405, "Tangible Personal Property Tax Return". Is DR-15 good enough for him to file for state tax in Florida and not to file for DR-405? Thank you.
