Filed my 2019 taxes and getting a refund but its still being processed. Will my stimulus check still be direct deposited based on the account info given on my 2019 taxes?

Yes, the IRS will use your 2019 tax return information to deposit your stimulus check into your bank account.  

Wow thank you so much I have been looking everywhere for this answer! Do you know if I will still get the stimulus check even if my return has been processing for more than 21 days? Does it matter? 

Once your 2019 return processes it will be used to calculate and distribute you stimulus payment.
