Can I change the bank account where my refund will be deposited after filing? I just realized that I entered the wrong bank account number

No you cannot change it after you file your return.

You cannot  change banking information while your return is in pending, nor can you change it after the return is accepted.

If you e-filed:

Banking information for direct deposit is wrong

If you entered incorrect banking information for your refund, you can change it if your return is rejected.  If it is accepted, however, it is too late to change it.  The bank will reject the refund and send it back to the IRS.  Then the IRS will issue a paper check and mail it to the address you put on your tax return.  Expect a delay of at least a couple of weeks to receive your refund.

You can't change the account, but if the IRS has not yet issued your refund, you might be able to stop the direct deposit by calling the IRS at 800-829-1040. They will then mail a check to you. However, it's been nearly impossible to get through to the IRS on the phone this year.
