Documents to include when filing taxes online

Hello,

New to TurboTax this year and wanted to have an idea of what tax documents I will need to include when I file my taxes online through TurboTax ? Will Turbo Tax at the end of my tax forms tell me what to include before I submit them online ? Just want to make sure when I submit to Federal and State I include any extra documents in addition to what Turbo Tax is doing on my behalf.

 

Thanks and look forward to the feedback.
