Hi there, Rak98.
Thank you for sharing the steps you've tried to solve the problem with 941 payment rejection due to the EFTPS password. Let me share some information about this and a fix that helps other users to get past this issue.
IRS is implementing new password requirements for making federal tax payments electronically. E-Pay gets rejected if the internet password is not updated or it doesn't comply with the new pin specifications. Some QuickBooks users were able to e-pay by resetting their password and by entering a new password with 12-30 characters. If your password length is less than this, I recommend updating it. For the complete guidelines, please check the EFTPS website: How do I get/replace/change my Internet password? (Step 4).
If you get the same result, I recommend contacting IRS to sort this out. From there, they can help reset your e-pay password. Once it's updated, please don't forget to also change your password in QuickBooks. You may refer to the steps provided by Adrian.
For additional reference, I've attached an article you can use on how to check the payment or form you submitted in QuickBooks: Check E-file or E-pay Status.
