I have entered bank routing and account numbers for taxes due and requested e-file. I think it has something to do with status of return listed as printed for filing. It has not been filed.
First you can check status of your return using this link https://turbotax.intuit.com/tax-tools/efile-status-lookup/
If it is e-filed the copy you have is for you to keep for your own records, on that copy your account and routing number shows xxxx for security reasons.
If you would like to confirm you can also update and verify your account and routing number in here
