Unfortunately, the Where's My Refund site has been erratic and unreliable. But if TT told you that the IRS Accepted your efiling for processing, then the government has it. (Approved is a later step, but TT receives no further updates once a return is Accepted.)
But, when checking, be sure to enter just the amount of your Federal refund. Do not adjust for state, nor for any TT fees coming out of it. Also see:
