I think you meant to say you efiled your taxes on March 30 and they were accepted. Accepted is the first step in the IRS process. Approval does not occur until the return is completely processed.
Unfortunately TurboTax gets no information about the status of your refund.
In normal times, the IRS says that most filers get their refunds within 21 days from the time their tax return is accepted.
Many returns are taking longer now since the IRS did not process returns for a while and there is now a big backlog of unprocessed returns.
Some press reports stated the IRS has started reopening offices and processing centers and are starting to process mailed returns again after not processing any for several weeks but no IRS press release has confirmed this.
They are now taking phone calls with a limited staff but it's hard to get through.
If you efiled your return, have you confirmed that the return was submitted by TurboTax and accepted by the IRS?
