It appears you have posted a similar query twice. My colleague has already answered. You can view her response through this link: https://quickbooks.intuit.com/learn-support/en-us/reports-and-accounting/re-how-can-i-manually-enter...

That does not work.

Just to let you know, the link you have provided assumes that the fundamental functional is working. It is not.  Vendors cannot set up their accounts to enter their ach information, and I cannot enter their data either.

I will contact support tomorrow.

Another option, sign up for a Melio account to compare and it's more reliable. You can ask your vendors to register their ACH details online to avoid errors. You can also get the cashback to pay bills.
