I used turbo tax debit card as direct deposit for my taxes last year. The account number the IRS used to deposit my stimulus check doesn't match. How i can figure out where my money went?

 Check the IRS website for status of the stimulus payment and update your bank information if necessary.

  AGI is line 7 on your 2018 return and line 8B on your 2019 return.  Refund is line 21a of the 2019 tax return. and line 20a for 2018

if the IRS attempted to direct deposit to a closed account, it would "bounce back" to the IRS and they would issue a paper check .

IRS website shows it was deposited already so I can't update the information. The account they used doesn't match what I had on file when I did my  taxes.
