Oh lord ... please seek local professional assistance to file the first business return since you are mixing up terms in your question. A C-Corp doesn't have partners, it has owners. And it files it's own tax return and pays it's employees and files payroll tax reports. Hopefully you have set up the books correctly so the return can be completed easily ... if not that is another reason to seek local education.
If you want to try it yourself .... you will need to use TT Business. This is only available for as a download and only for windows environments. https://turbotax.intuit.com/small-business-taxes/
