Understanding Turbotax Support Options (Community/Discuss/TurboTax Staff)

I am new to Turbotax - I wonder if you can guide me through the basics of support options. I see that there is a Community/Discuss option where you can search for prior responses to questions or ask new questions. There is also a "Support" tab on the top right - Is this to intended to ask questions to TurboTax Front Office/Staff? Finally, how do I find tax preparer's (or CPAs) who can help me with Turbotax. I was told there is Turbotax live but it is LIMITED to the current tax year? Thank you
