TurboTax does not get any additional information about your return/refund once your returns are accepted. The program has no idea if you received your original refund or if you return was processed. TurboTax has also not idea if you received your return, the program will also show your refund amount until you do an amendment.
The IRS does state that you should not file an amened return until your original return has been fully processed (refund received or payment withdrawn).
