If my full bank account number was not added to my tax return, how do I change it before it’s sent? The amend option won’t let me do it and I can’t to wait extra 3 weeks?

Please explain exactly what you have done so far.   Did you e-file your tax return?  Was it accepted by the IRS?   If it was accepted you cannot change the banking information.   If it was rejected, you can change the banking information but do NOT click on anything that says "amend."  You do not click on "amend" to fix mistakes on a return that has not been filed or fully processed.
