This is not uncommon. Accepted in TurboTax just means that they have received your return. That is the status of your return; not your refund. Until that state starts actually reviewing and processing your received return, they won't have any record of it when you go to check status on their website. They no longer provide updates to TurboTax once they accept your return.
The next step would be for them to review/process the return and approve your refund. Once they complete processing of the return, then they will update their system and you can track it on their site. Processing times vary from state to state.
Some states put a notice on their refund tracking page to let you know how long processing takes; some do not.
