The IRS would not say your return is processing if they had not received it and started to process it. I think your IRS agent made a mistake. Did you tell the agent when you talked to the IRS that you had checked the Where's My Refund web site and it said the return was being processed?
Here is the procedure the IRS uses after a return is accepted: https://www.irs.gov/refunds/tax-season-refund-frequently-asked-questions
There is nothing TurboTax can do for you if everything in the TurboTax files say it was efiled and accepted. TurboTax can't resend an efiled return that has already been efiled and accepted. It would just be rejected by the IRS.
