If your LLC is a single member LLC (only you) then you can file your LLC business taxes with your W-2 income on your personal tax return. It looks like you are using Self-employed which is what you need in order to do this. Your LLC business is self-employment/sole-proprietorship and is reported on Schedule C. Single member LLC do not need to be prepared separately from your personal return.
However, if your LLC is a multi-member LLC, you will need to file a separate business return using TurboTax Business software. The LLC will issue you a K-1 and the K-1 gets reported on your personal tax return. https://turbotax.intuit.com/small-business-taxes/?srqs=null&cid=ppc_gg_b_stan_all_na_business-2018-F...
