Once a tax return has been Accepted by the IRS or a State, TurboTax receives no further information concerning the tax return or the status of any tax refund. 

If accepted by the IRS use the federal tax refund website to check the refund status - https://www.irs.gov/refunds

After the tax return has been Accepted by the IRS (meaning only that they received the return) it will be in the Processing mode until the tax refund has been Approved and then an Issue Date will be available on the IRS website.
See this IRS website for federal tax refund FAQ's - https://www.irs.gov/refunds/tax-season-refund-frequently-asked-questions

I have the same issue, filed my taxes on April 10th using Turbo Tax and got confirmation that my return has been accepted. It is May 14 and still havent received my federal refund. I have checked the IRS refund status website and nothing there..

Please adivse.. Does this mean I am being audited ? or is the wait so long now a days ?

No, it does not necessarily mean you are being audited. Please see What if my IRS refund is taking longer than 21 days? for more information, including contact numbers for the IRS.
