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. Some refunds take longer.
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. The IRS is currently not processing any mailed returns.
