After you file

@Wallesh This thread has had no activity since 2023.   If you mean that your 2024 refund was refused by the bank because of incorrect banking information, you will be waiting for several weeks or more for the IRS to mail you a check.  That does not mean you are being audited.  

Here is what the IRS says about entering incorrect banking information

If your refund is sent back to the IRS—- make certain that the address you entered on your Form 1040 is correct.  And…open all mail, even if it looks like junk mail.

And.....

If you chose to have your fees deducted from your federal refund, but entered wrong or closed bank account information for your direct deposit, you are going to have an aggravating, frustrating situation.  Your refund will go back to the third party bank. The third party bank might issue and mail you a check, or they might send your refund back to the IRS and then you will have to wait for the IRS to mail you a check.

  If the third party bank mails the check, it will come in a plain envelope via first class mail so make sure you open all mail and do not assume anything is junk mail without opening it.  While you are waiting, make sure that the address you entered on your tax return is correct, or your problem will be even worse.
