How to get my taxes reviewed?

Hi there, I spent a lot of time entering all my taxes info in my Turbo Tax Premier Desktop (Mac) version and am just waiting for the 1116 form to complete. But I am worried about a few numbers that did not match (for e.g. RSU amount in box 14 of w2 vs total Adjusted Ordinary income for RSUs sold in my ETrade supplement vs. amount computed by Turbo Tax for RSUs to be included in wages) . Hence I feel that it may help to get it reviewed before submitting just to ensure that I have not missed anything. 

1) Is upgrading to TurboTax Live the best way to get it reviewed?

2) Is it possible to get it reviewed even though I used TurboTax Premier desktop version and not online?

3) What may be the cost for just getting my TurboTax returns reviewed and any corrections made as I have already pretty much entered everything?

Thank you.
