How do I file personal and LLC taxes as a first-timer?

[Devante S.]

Hi everyone, maybe a rookie question here, but I had a W2 for a good portion of 2023 and also had a self-employed business for the other half. How exactly do you file taxes when you have a 9-5 but also generate income from self employment? Maybe some of you here who kept a day job but also generate income from investments can help me understands the basics of this. My primary question is whether I should do completely separate filing or if I need to do this all together at once so as to report all income and deductions on one single filing, or if I can treat this as separate entities. 

I'm hoping this also helps me lay a better ground work for how taxes may work as I grow as an investor.

Thanks in advance.
