You do not need to file a tax return.

According to the IRS:

The IRS does not have my direct deposit information. What can I do?

In the coming weeks, Treasury plans to develop a web-based portal for individuals to provide their banking information to the IRS online, so that individuals can receive payments immediately as opposed to checks in the mail.

The bank account info on my 2018 is WRONG. I need to change it.

your tax software won’t allow me to change it. It’s to a prepaid card turbo tax sent me and I don’t have that card anymore

please help me change the bank account with the irs 

There is not yet a way to update this information with the IRS.

We are still waiting for IRS guidance regarding updating or providing direct deposit information for the stimulus payments.

We will have more information once the government finalizes the details.
