Accepted only means the IRS verified some basic info on it so they know it's really from you. After it is Accepted Turbo Tax is done with their part and does not get any updates from the IRS. The IRS processes it then approves it before they send the refund.
The IRS lookup website is unreliable and not always updated and is glitchy. Many people are still waiting. It may take 6 months or more for the IRS to process your return.
