Since the IRS ( for Federal return ) and State ( State return) do the processing and the issuance of the refund amounts, the horse's mouth in each case is "Where is My Refund" ( IRS) or similar ( for your state ). Anything else is derived from these sources. Please consider visiting the WMR at the IRS and similar site of the State.
Of course , if you have refund based advances/loans then there are other entities involved.
