The IRS started accepting Form 8910 (fuel cell vehicle credit) on January 22nd. But, while using TurboTax, it says I have to wait until March 30th to file my taxes! Why?

I can't figure out why I can't complete my refund? I spoke with the IRS, finally, today and they said there should be no reason for my filing to be held up until the end of March. Does anyone know why I can't finish filing through TurboTax? Thank you for any help or input. This has been a bit frustrating
