I thought I agreed to pay tax owed through turbotax but there is nowhere to see if that in fact happened. Or do I need to pay it through IRS directly?

There is no way to look this up, even on my 1040. It just says tax due. I could have sworn I selected to pay that through bank account on turbotax after e-filing but there is no way to check through records. Or does this not exist and I have to pay directly through IRS website?
