I, too , am having the same problem. My numbers are absolutely correct, yet Turbotax will not accept them. This has to be a problem with the program. Come on, experts! Admit that there is a problem and do something about it!
Edit (3/30/21):
I was able to finally solve this problem as follows (download version):
Go to Tools>My Tax Data>Info Wks, Routing number.
Click on that entry, then click on Go to Form. You'll find both numbers there and they can be edited. Click on "Close Form" when finished.
I found an error in my account number on this form, fixed it, and was able to e-file.
