Direct Debit

When doing a final review of my federal taxes, I get an error message regarding the federal information work sheet that states: "Direct Debit check box should not be checked. Only electronically filed returns are eligible for direct debit."

 

I will owe money for the federal return and want to have the amount taken out of my checking account. I entered by bank information and checked the direct debit box.  Why am I getting this message?
