You must have both the routing number and account number from your tax return to know where the IRS will direct deposit your refund. Look on your federal form 1040 near the signature line for the banking information. You can also find it near the top of the filing instructions.
To get back into your return after printing or e-filing, please follow these steps:
1. In TurboTax Online, sign into your account.
2. Select Tax Home in the left menu.
3. Scroll down to Your tax returns & documents.
4. Select 2019, and then select Add a State (You're not actually adding a state, this just gets you into the right menu).
5. Once you're in your return you can navigate around as usual.
If you no longer have the account shown on your tax return, the bank will decline the deposit and the IRS will issue a check and mail it to you at the address on your tax return.
