If the routing and account numbers are marked out on your return you've printed for mailing, there's no way the IRS would be able to direct debit your account for your taxes owed.
I'd mail your return that you have prepared, along with a check for the tax liability. OR (a better option, in my opinion), use IRS Direct Pay to pay your tax liability and avoid mailing your personal check. It's a quick and easy electronic option. I'm linking that info below.
