No, this is not a glitch. Your bank routing number and account number are only supposed to show on your 1040 Form if you are getting a refund.
If you chose to pay your balance due via E-pay (Direct Debit), your bank account information should be shown on your Filing Instructions page, in the Balance Due/Refund section. For direct debit, you will see the payment amount, your bank routing and account numbers, and the withdrawal date (if you did not select a date, the debit date will automatically default to 04/17/2018).
Within the TurboTax program, you will find your direct debit bank account information in the section labelled Federal Information Worksheet Part V - Direct Deposit or Direct Debit.
