If your 2019 return is still processing AND you did not file a 2018 return then the stimulus check will take a bit longer until the 2019 return has finished processing. Nothing you or anyone else can do to speed up the process. Check these sites for updates:
Accepted is just the first step in getting your tax return processed by the IRS. After it is accepted, the IRS begins processing it and after that is completed, the return will be approved and the refund sent. This is taking a long time for many filers. See this for a description of the process: https://turbotax.intuit.com/tax-tips/tax-refund/wheres-my-tax-refund-the-irs-refund-timetable-explai...
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.
The IRS is currently not processing any mailed returns and is not taking any phone calls.
