Get your taxes done using TurboTax

My tax returns were rejected and I reached out to TurboTax for help and went up the rank until I reach a CPA.  There were no errors in the return until she made some changes.   She wasn't able to correct the errors.  She told me that I need a line-b-line review but she didn't know how to connect me with someone to do such a review.  She suggested the maybe I need to upgrade from a Deluxe to a Premium in order to get this type of service.  I did and my upgrade order was confirmed right away after I paid for the upgrade.  She still couldn't find a link to how I can request a line-by-line review.  I lost the connection.   If a CPA from TurboTax can't correct the mistakes in my returns, what hope do I have in trying to do so myself?!  Please help.
