The IRS may not give you the stimulus payment until they complete processing your tax return. Accepted only means that the return was submitted to the IRS and they checked your name and SSN and determined you were eligible to efile. The next step is for the IRS to process your return and then approve it. There is a large backlog of unprocessed returns due to slowdowns from the virus.
If you efiled your return, have you confirmed that the return was submitted by TurboTax and accepted by the IRS?
