I need to amend my tax return

I need to change my direct deposit account number as well as the address and phone number on my taxes

Once you have filed you cannot change anything on the return.  When you file the 2020 return you will have the chance to update everything.   The only thing you can change is the address ... file a form 8822 with the IRS ...

You are not mentioning anything that would require amending a tax return.  And you cannot change banking information after your tax return has been filed.  When you prepare your NEXT return you can change your banking information.

If you need to change your address you can file a change of address with the IRS.
