Only the IRS and your State control when and if a Federal or State tax refund is Approved and Issued.

To check the status of an e-filed return, open up your desktop product or log into your TurboTax Online Account. You can find your status within the TurboTax product.

If accepted by the IRS use the federal tax refund website to check the refund status - https://www.irs.gov/refunds

If accepted by the state use this TurboTax support FAQ to check the state tax refund status - https://ttlc.intuit.com/questions/1899433-how-do-i-track-my-state-refund

Due to the pandemic and the stimulus payments being handled by the IRS, the IRS has delayed the processing of many tax returns.

Stimulus payments are being made throughout the year, but there has not been an absolute timeline for issuing the payments shared by the IRS. 

There is now a tool available through the IRS site link below that will allow you to check the status of your stimulus payment.  It is called Get My Payment.
