My total return was supposed to be 500

Your "total return?"  Do you mean your total refund?

Federal and state refunds come from completely separate entities,  There is no rule as to which one will come first or how much time there will be between their arrivals.

STATE RETURN

Once your federal return has been accepted by the IRS, only the IRS has any control. TurboTax does not receive any updates from the IRS. Your ONLY source of information about your refund now is the IRS.

You need your filing status, your Social Security number and the exact amount  (line 20 of your Form 1040) of your federal refund to track your Federal refund:

You mean your Refund?  For federal or state?  Federal and state  refunds comes from different places at different times. If the IRS or state adjusted your return they will mail you a letter.
